A new £5 note officially comes into circulation in the United Kingdom on Tuesday, marking the first use of plastic in the history of British currency.

Dubbed "The New Fiver" by the Bank of England, the note was first unveiled by BoE governor Mark Carney at a ceremony in June, but it now officially available for British citizens to use.

The note features an image of former Prime Minister Winston Churchill alongside one of his most famous quotes: "I have nothing to offer but blood, toil, tears and sweat," on one side, and an image of Queen Elizabeth II on the other.

The use of polymer — a form of plastic — marks the end of 320 years of the use of cotton paper in Britain's bank notes. It has been introduced to increase the durability of the notes, as they are now waterproof and harder to tear. The plastic £5 notes are also more difficult to counterfeit than paper ones and have been manufactured by British banknote maker De La Rue.

Business Insider picked up some of the new fivers on Tuesday to see exactly what they're like, and had a go at burning, tearing, and submerging them in water. This is what we found:

It feels and looks a bit like monopoly money — I wasn't sure if this is just because it is new and unknown but the money looks and feels slightly fake at first. It takes some getting used to.

It is noticeably smaller than the old note

Size-wise, the new note is probably about 1cm narrower and 0.5cm shorter than one of the cotton paper fivers. According to the BoE, the surface area is about 15% smaller. That may not sound like a lot, but its very noticeable. One BI reporter instantly commented on the size, saying it looked "tiny."

They stick together — I picked up six new £5 notes and they clumped in my pocket, making it difficult to separate. Making it rain in the club could prove tricky with the new notes.

"Captain America: Civil War" is finally out on Blu-ray and DVD.

Just how much do you know about the making of the film?

INSIDER went through the Blu-ray commentary featuring co-directors Anthony and Joe Russo and screenwriters Christopher Markus and Stephen McFeely to get an inside look at what it took to bring the highest-grossing movie of the year so far to the big screen.

Keep reading to see what we learned.

The Winter Soldier's mind control backstory was almost more complicated.

At the beginning of the film, we're shown a flashback of the Winter Soldier/Bucky Barnes getting brainwashed by a series of words. He's in some sort of brain control chair, and according to screenwriter Christopher Markus, it almost played a larger role.

"There were many drafts where they were chasing something called the mind crown, basically that thing that goes over his head," says Markus. "And then somebody very wisely said, 'Couldn't it just be like a notebook with some words in it?"

The screenwriters picked the Winter Soldier's mind control words somewhat carefully.

Nine words repeat themselves on screen throughout the movie to trigger a brain control mechanism for The Winter Soldier.

"I think we picked Russian words that sounded interesting. Had some chewiness to it. And then, even when you read them it wasn't, you know, kittens, puppies," said Stephen McFeely.

Markus added that they looked at how the words read in English to "make you think you were watching something cool."

You're not supposed to know whether to side with #TeamCap or #TeamIronMan by the end of the film.

"Captain America: Civil War" pits the two superheroes against one another and if you thought you were supposed to side with one more than the other by the film's end, you were wrong.

Co-director Joe Russo said one of the most difficult things about making the film was balancing Captain America and Tony Stark's roles to make sure each one felt as if they had an equal voice in the film and that their points of view were equally represented. 

"By the time we got to the end of the movie you're left with a very complicated choice to make. You couldn't tell who was wrong and who was right and hopefully you left the theater and argued with your friends and family about who was wrong and who was right," he explained. 

There are few things more important than fertility in determining a nation's future viability.

Demographers suggest that a country needs a fertility rate of just over two children per woman to hit "replacement fertility"— the rate at which new births fill the spaces left behind by deaths.

But due to certain cultural and economic forces, only about half of the world's 224 countries currently hit replacement fertility.

For those that don't, encouraging people to have sex can involve strategies that range from highly explicit to downright bizarre.

Is that Boyz II Men I hear?

Denmark

If you aren't going to have a kid for your own family, Danes are told, at least do it for Denmark.

No, literally, do it for Denmark.

The small Nordic country has such a low fertility rate — around 1.73 children per woman — that Spies Rejser, a Danish travel company, has come up with ingenious incentives to convince people to get pregnant.

First, it offered to provide three years' worth of baby supplies to couples who conceived on a vacation booked through the company.

Now it's come up with a sexy campaign video entitled "Do it for Mom," which guilt trips couples into having kids to give their precious mothers a grandchild.

Russia

Vladimir Putin once brought Boyz II Men to Moscow to rile men up right before Valentine's Day.

Can anyone blame him? As Tech Insider recently reported, the country is experiencing a perfect demographic storm. Men are dying young. HIV/AIDS and alcoholism are crippling the country. And women aren't having babies.

The problem got so bad that in 2007 Russia declared September 12 the official Day of Conception.

On the Day of Conception, people get the day off to focus on having kids. Women who give birth exactly nine months later, on June 12, win a refrigerator.

Japan

Japan's fertility rate has been below replacement since 1975. 

To offset that decades-long trend, in 2010 a group of students from the University of Tsukuba introduced Yotaro, a robot baby that gives couples a preview of parenthood.

If men and women begin thinking of themselves as potential fathers and mothers, the students theorized, they'll feel emotionally ready to take a stab at the real thing.

Whataburger is to Texas what In-N-Out is to California. Both companies are still family-owned, regional chains — an anomaly in a market that's dominated by national multimillion-dollar fast-food companies.

In-N-Outs are scattered throughout the Southwest, while Whataburger locations line the South from New Mexico to Florida. They meet in the middle, in Dallas, Texas, where I ate both side by side in a taste test.

While Texans swear by Whataburger's more Southern menu items — Texas toast, patty melts, biscuits — Californians rave about In-N-Out's fresh ingredients and "animal-style" burgers. I ordered a burger, large fries, and a chocolate milkshake.

My first stop was Whataburger. The building is outlined in a classic orange trimming, making it hard to miss when you're cruising down a Texas highway at 80 mph.

Part of Whataburger's Southern charm is displayed right on their windows. There's an American flag and posters repping the neighborhood sports teams.

They take pride in their history — found in most Whataburger restaurants is a framed portrait of the chain's founder, Harmon Dobson, and the original location, which opened in Corpus Christi, Texas, in 1950 (right).

For those wanting to soak up more than sun on their next trip, a visit to a museum is in order. But with an estimated 35,000 museums in America, it can be hard to choose which one to see.

Luckily, TripAdvisor just released its list of the 10 best museums in the US, which is based on millions of TripAdvisor reviews from travelers.

From the Smithsonian National Air and Space Museum in D.C. to the Art Institute of Chicago, here are the best museums in the country.

10. American Museum of Natural History – New York City, New York

Admission: Adult – $22; Senior, Student – $17; Child (2-12) – $12.50; Child Under 2 – Free

9. National Gallery of Art – Washington, D.C.

Admission: Free

8. Kennedy Space Center Visitor Complex – Titusville, Florida

Admission: Adult – $50; Seniors, Military – $46; Child – $40

There's a number of ways students can show pride in their school, but nothing shows school spirit quite like showing up on gameday. 

Whether it's for a basketball game, football game, or a smaller niche sport, students celebrate their schools by covering themselves head-to-toe in school colors and filling stadium seats. They tailgate long before the games starts and continue celebrating well after it's over. 

The Princeton Review recently released its 2017 college rankings. They had over 140,000 students fill out a survey containing more than 80 questions. One question was, "How popular are intercollegiate sports at your school?" From those results, they determined the 20 schools where "Students Pack the Stadiums."

Keep reading to find out the 20 colleges with the most school spirit in the country.

Ever wonder what to say when the hiring manager asks tough questions like, "Who do you admire, and why?" or "Is it ever OK to lie in business?"

If so, you've come to the right place.

Business Insider recently flipped through "Why You?: 101 Interview Questions You'll Never Fear Again," a book authored by James Reed, who is the chairman of Reed, a top job site in the UK and Europe, and found some of the best responses to the trickiest queries.

In his book, Reed shares one or two ideal answers to questions you're likely to be asked during a job interview.

You don't have to memorize and repeat these verbatim (of course, your answer will depend on your specific situation and the job you're interviewing for), but these should help you come up with the perfect response to some of the toughest questions.

Some of Reed's sample responses have been edited for length or clarity.

SEE ALSO: The most common questions hiring managers ask during job interviews

'Is it acceptable to lie in business?'

Reed explains in his book that the interviewer is trying to understand what your core values are when they ask this question.

He says you'll want to "show that you leave lying to people who are content to win that way."

He suggests answering with something like this:

"It's never OK to lie. People do, of course, usually for some short-term gain, but I don't think it's ever worth it in the long run. It's easy to make bad choices under pressure, and some businesses are even run in such a way that people don't know they're lying. I prefer to treat people the way I want to be treated myself, and nobody wants to be lied to. Life's much simpler if you always tell the truth. And more people will forgive you for making a mistake, but they'll never forgive a lie."

'What are your greatest weaknesses?'

Reed says "there's no quicker way to break the rapport between you and your interviewer than to give a clichéd answer to this question, or to pretend, as many do, that your weaknesses are trivial and irrelevant."

Don't be dishonest or insincere — but be careful not to highlight a flaw that would make the hiring manager think you couldn't do the job at hand.

Reed offers to following response:

"I'd say my greatest weakness so far as you're concerned is that I've been out of the workforce for a couple of years in order to raise my family. I didn't drop out of the industry altogether during that time, though. My contacts book is up to date and I've kept up with industry trends. For example, I enrolled for online professional development courses with [give examples]. That's something I wouldn't have had time to do if I'd been at work, so in a way being out of the workforce has done me some good. If you take me on, I certainly don't think I'll need retraining."

'What career regrets do you have?'

On the surface, this might seem like a harmless question, but Reed says the interviewer is really asking, "Is there something bad about you that I cannot see, and if there is, can I get you to admit it? Do you carry psychological baggage that you don't need? How readily do you forgive yourself — and others?"

Reed suggests giving the interviewer "a little bit of grit," but says you should never use the word "regret."

"Regret is a loaded word: don't point it your way," he writes.

Instead, Reed says you should "focus on something positive and say you wished you'd done more of it. Then stop talking."

Here's an edited version of the sample answer Reed offers in his book:

"All told, I don't have too many complaints about the way things have gone. If I could change one thing, I'd have moved into the cell phone insurance business sooner than I did. I turned out to be good at that, and I enjoy it too. ... If I'd moved into it sooner then maybe I'd have been sitting here a couple of years earlier — but who knows? Missing out on that taught me to take the odd risk in life, and I'm thankful for that."

Buying a home that needs extensive remodeling can fetch a handsome discount, but it depends a lot on where you're looking to buy.

In much of America the discount won't make up for significant renovation costs. The average fixer-upper in the US only nets a decrease of 7.6% from the median list price, which works out to just $11,000 in cash savings, according to analysis from real estate marketing firm Zillow. 

But in some cities, homes needing work offer savings of two to three times that much. Zillow analyzed 70,000 listings of fixer-uppers across the country — identified using key words like "fixer-upper,""TLC," and "good bones"— and compared list prices to estimated market values to determine which metro areas provide the best deals.

Expensive markets, where even a modest percentage discount amounts to significant savings, tended to provide the most value on the median fixer-upper home: Cash savings averaged $54,000 in San Francisco and $38,000 in San Jose, the two highest figures on Zillow's list.

Business Insider rounded up the top 10 metro markets from the study, ranked by the average amount of money saved.

If you feel like you're having deja vu at theaters lately, you're not totally wrong. 

Studios have been relying on pre-existing properties in order to pull in audiences. Disney has built an entire cinematic universe around Marvel. Meanwhile, sequels that nobody was really asking for, like "Jurassic World," or "Mad Max: Fury Road," ended up as smash hits.

But this isn't always the case.

There's an onslaught of sequels, remakes, and reboots and they're not slowing down any time soon. Here are some of the recent ones you may have missed and others which will be coming to theaters soon.

"Zoolander 2"

"Zoolander" was overlooked when it was first released in theaters, only to build its fanbase in the coming years and become one of the most quotable comedies of the new millennium. "Zoolander 2," which was hammered by critics, proved that maybe once was more than enough for Derek Zoolander, Hansel, and Mugatu.

"Alice Through the Looking Glass"

Negative reaction aside, Tim Burton's 2010 update of "Alice in Wonderland" nevertheless grossed over $1 billion worldwide, which was enough to merit a sequel.

The resulting sequel, from a different director, was instantly forgettable and universally reviled. It turned out to be one of the biggest duds of summer 2016.

"The Legend of Tarzan"

Despite a powerhouse cast that includes Samuel L. Jackson, Christoph Waltz, and Margot Robbie, the film barely resonated, raking in $356.4 million worldwide. It's a bland reboot that also happened to fall in the shadow of the far superior "The Jungle Book," which came out in April. Stick to the 1999 animated Disney version of "Tarzan" instead. 

On Tuesday, General Motors revealed the range of its Chevrolet Bolt EV, its first mass market, affordable, electric car.

The Bolt, which goes into production this year, will be able to drive 238 miles per charge, beating Tesla's Model 3 range of 215 miles per charge. GM's EV will go into production this year, also beating Tesla's Model 3 to market. The Model 3 is slated to go into production in late 2017.

The Bolt will price at about $30,000 after a $7,500 federal tax credit and will have a top speed of 91 miles per hour. While that’s impressive on its own, the vehicle also has a number of other impressive features that make it much more appealing.

We had a chance to test drive the Bolt EV at CES in January with Stuart Norris, one of the Bolt’s designers. Norris walked us through some of the car’s best tech and design features.

SEE ALSO: The Chevy Bolt has a 238-mile range — but it still doesn't compare to Tesla's Model 3

There's a 10.2-inch touchscreen display infotainment center and an 8-inch display in the driver's console.

The main display, which is customizable, serves as the control center for most functions inside the vehicle. 

“We really want the driver to live in this screen, so they’ve always got a little bit of the information that they want to have," Norris said.

The car also has wireless charging in the console.

There's also two USB ports in the console so you can plug in your smartphone to connect to Apple CarPlay or Android Auto. 

The car is always connected via low-energy bluetooth, allowing the driver to be connected to the car via the app at all times.

Chevrolet's mobile app lets drivers check on the vehicle's charge, remotely start their car, and pre-condition the cabin, among other things. The car's key fob also uses Bluetooth for keyless entry and ignition.

If you compare yourself to certain people, it's easy to feel you're unsuccessful. If you're an entrepreneur and you compare yourself to Richard Branson, you lose.

If you're a musician and you compare yourself to Taylor Swift (especially if the point of comparison is earnings), you lose.

If your goal is to change the world and you compare yourself to Steve Jobs ... you lose.

That's the problem with comparisons. No matter how successful you feel, there will always be someone who is more successful. There will always someone better, or smarter, or wealthier, or seemingly more happy.

So let's stop comparing and just focus on you. Here are a few signs that you're more successful than you might think — and, in all likelihood, happier too:

SEE ALSO: 6 lies you tell yourself that are keeping you from success

1. You have enough money that you can make positive choices

Many people live paycheck to paycheck. Worse, many have to decide between necessities. (My wife just mentioned the other day how once upon a time she had to decide between filling a prescription for an antibiotic or putting gas in her car.)

If you make enough money, and don't spend so much money, that you can make positive choices about what to do with some of it--whether it's investing, or taking a vacation, or taking classes...anything you want to do instead of have to do--then you're successful, both because you've escaped the paycheck-to-paycheck grind and because you can leverage that extra money to become even more successful.

2. You have close friends

Close friendship are increasingly rare; one study found that the number of friends respondents felt they could discuss important matters with has dropped from an average of 2.94 to 2.08 in the last 20 years. (So much for the power of social media.)

If you have more than two or three close friends, be glad, not only for the social connection but also because the positive effect of relationships on your life span is double what you get from exercising and just as powerful as quitting smoking.

And where professional relationships are concerned ...

3. You choose the people around you

Some people have employees who drive them nuts. Some people have customers who are obnoxious. Some people have casual acquaintances who are selfish, all-about-me jerks.

Guess what: They chose those people. Those people are in their professional or personal lives because they let them remain.

Successful people attract successful people. Hardworking people attract hardworking people. Kind people associate with kind people. Great employees want to work for great bosses.

If the people around you are people you want to be around you ... you're successful. (And if they're not, it's time to start making some changes.)

Cutting back and opting for frugal alternatives may help you save money initially, but is going with a more affordable option always best?

It could be, but not necessarily. There are instances where your cost-cutting measures can backfire and you may end up paying more than you anticipated.

Here are five ways common cost-cutting methods can backfire.

SEE ALSO: 6 shopping mistakes that can keep you from a good deal

DON'T MISS: 10 items that lose value the more you spend on them

1. Going extreme with coupons

Coupons can save you a significant amount of money. However, for frugal-living expert Lauren Greutman, doing so backfired in a big way when she took the couponing a bit too far.

"When I was trying to get out of debt, I'd spend too little money at the grocery store. I would only use coupons and try to save money as much as I could," she says.

However, only using coupons to buy things cut her budget to the bone, which left her hungry for more — literally. "I'd resort to ordering takeout," she says.

When paying off debt and using coupons, Greutman recommends a more balanced approach to budgeting and saving money. For example, consider meal planning and being realistic about what you need for a healthy diet.

2. Switching to a low-cost phone provider

Many people have smartphones, but depending on your plan, data can be costly. When you're looking at your phone bill and see an attractive offer elsewhere, you may be tempted to jump ship and opt for the cost savings.

However, switching plans doesn't always work out to be cheaper.

Jason Vitug, founder of personal finance website Phroogal.com, (full disclosure: I'm currently working for and with Jason as an event planner) says he switched cellphone companies to cut his costs in half — but ended up with bad service.

"It turned out to be a hassle, and the network isn't as friendly for travelers. As I depend on my smartphone to conduct my business, I should have considered much more than saving dollars by switching," he says.

Ultimately, this switch could end up being frustrating when you can't communicate with loved ones or run your business, and it can become costly if you have to pay fees for additional coverage areas or features.

If you're looking to save money on your current phone plan, consider calling up your service provider and asking for a discount. There's no harm in negotiating. And if you do opt for another provider, do your research on the company's service, options and pricing to be sure you're getting a better deal than you already have.

3. Downsizing to a cheaper car

Vehicles can be expensive, and one way to minimize costs is to downgrade and get a cheaper car. Instead of having a nicer, newer car, why not opt for something more affordable?

While downsizing to a cheaper car may feel like the right option to save money, it's not always your best bet.

"When we first started our debt-free plan in August 2013, we decided to sell my husband's car, a 2004 Subaru WRX, and buy a cheaper car for him to drive," says Monica Louie, founder of personal finance blog OurDebtFreeFamily.com.

After purchasing the cheaper car, though, trouble started to roll in. "Within a couple of weeks, the check-engine light came on," she says.

The "deal" ended up not being worth it in the long run, with all the repairs required, not to mention the hassle and stress of having a car start breaking down shortly after buying it.

"We learned that we always need to do our due diligence when making a large purchase like a car and always get a second opinion, no matter how great of a deal we think we're getting," Louie says.

There's been a little reshuffling for the top spot of this list.

Now that we know all about the new iPhone and we've had some time to evaluate it, we can finally add the iPhone 7 into the ranks.

20. BlackBerry Passport

The BlackBerry Passport may look strange, but a lot of BlackBerry fans seem to love it. It has a really nice physical keyboard, but the key feature is its unique square design.

Price: $450

19. BlackBerry Classic

If you were a BlackBerry fan back in the company's heyday, you're going to love the BlackBerry Classic. It looks similar to older BlackBerry models, but features a sharp touchscreen and an excellent physical keyboard.

Price: $290

18. Microsoft Lumia 950

If you must have a Windows phone, there's only one device to consider: Microsoft's Lumia 950. Although reviews were pretty bad, this phone does hold some promise for people who need Microsoft apps to do everything. It also has a really nice camera and can connect to a keyboard, mouse, and monitor and let you run a lightweight version of Windows.

Price: $427

This fall is jam-packed with new options. In order to help viewers make up their minds, we're naming the shows we're most looking forward to.

There are remakes like Fox's "Lethal Weapon" and "The Exorcist." There are spins on what worked last year, such as true-crime docuseries like CBS's "The Case of: JonBenét Ramsey." Or quirky niche comedy like FX's "Atlanta."

We've watched all the premiere episodes made available to press or we've seen the trailers. In some cases, we've even spoken to the people behind the shows. There were some shows that we had dismissed in theory, but then they ended up pleasantly surprising us.

Here are the 20 best new TV shows this fall based on what we've seen:

"Loosely Exactly Nicole" (MTV), Mondays at 10:30 p.m.

Writer and stand-up comedian Nicole Byer has a really infectious energy in this sitcom loosely based on her own life. She's an overweight black woman trying to make it in Hollywood, and Byer doesn't mind pushing the envelope of taste.

"Atlanta" (FX), Tuesdays at 10 p.m.

Donald Glover delivers in his return to series television after bailing on NBC's "Community." The good thing is "Atlanta" is worth every bit of the three-year wait viewers endured before it finally debuted. This semi-autobiographical take on Glover's hometown follows his character Earn as he teams up with his rapper cousin to make something of themselves. It's both deeply intimate and hilarious.

"One Mississippi" (Amazon), Streaming now

Absolutely no one has had worse health luck than comedian Tig Notaro. Somehow she rolls all that suffering, then adds the death of her mother, into a fully unique take on life and family on "One Mississippi." The series marries grief with humor, and Notaro's incredibly relaxed voice leaves viewers with new tools in dealing with life's messiness.

Air travel comes with its fair share of pain points. Your checked bag can't be over 50 pounds, so you might be forced to switch items between bags when you get to the check-in counter. Airports are also notorious for their lack of outlets, so you'll often see groups of people forced to hover around central charging stations.

In his mission to build a bag that would solve those traveling blues, Raden CEO Josh Udashkin observed travelers at the airport, taking note of what stalled their journey, he recently told Business Insider. The final design is a sleek, lightweight, and incredibly high-tech suitcase that has its own app and can charge your phone, weigh itself, and tell you its approximate location.

Raden sold $2 million worth of bags in its first four months of operation. It has raised $3.5 million from First Round Capital, Lerer Hippeau Ventures, and private investors to alleviate those struggles that can make traveling a stressful, hectic mess. 

Below, we take a close look at their A22 Carry case and tell you if it's worth the $295 price tag.

Raden was thoughtful about its design and branding. The A22 Carry suitcase arrives in a branded bag that you can keep for storage when you're not traveling.

You're greeted with a simple three-step process for hooking up your bag: 1. Turn on the battery. 2. Download the app. 3. Pair your case with the app so that it knows this is your bag.

TripAdvisor has just released a list of the best museums in Europe as part of its 2016 Travellers' Choice Awards.

The travel website determined which museums are worth visiting on the continent based on the quality and quantity of millions of user reviews left in the last year.

From a museum on a crumbling archeological site to a grand palace with a famous art collection, here are the top 15:

15. History buffs enjoy visiting Churchill War Rooms in London, where Winston Churchill met with Cabinet members during the Second World War. Visitors can walk around the bunker and learn more about the history of the rooms in an accompanying exhibition.

14. London's Natural History Museum is most famous for its impressive dinosaur displays, but the building itself is worth visiting for its distinctive gothic architecture alone. On the last Friday of each month, visitors can stay late to spend a night at the museum.

13. The walls of London's National Gallery are lined with masterpieces by Monet, Titian, Canaletto, Vermeer, Turner, and more. It's also a beautiful building in which to look at art.

While a master's degree in business administration (MBA) can act as a ticket to a high-paying job, the courses do not come cheap.

And some are better value than others.

To find out which provide the best value for money, salary-benchmarking website Emolument, analysed the pay of 1,020 MBA holders, and the cost of their education, calculating the return-on-investment of the course for one year of employment.

America and the UK dominate the list, but France and Hong Kong also feature.

Here is the ranking:

Thanks to Uber, it's finally possible to experience riding in a self-driving car.

Starting Wednesday, the ride-hailing service is allowing select users to hail its self-driving cars in Pittsburgh.

You'll need a special invite to try it out, which Uber says it's only sending to its "most loyal" customers. Uber declined to fully clarify what qualifies as loyal, saying only that it was determined by the number of rides hailed.

Where you tend to hail a ride factors into whether you're getting an invite, as Uber's cars navigate only in limited areas, like downtown Pittsburgh and the Shadyside neighborhood, which is north of downtown.

Caveats aside, it's a big deal in the self-driving-car space. This is the first time members of the public can experience the technology firsthand, and the first time we can see how people really feel about these cars hitting the roads. (In case you were wondering, Tesla's cars can drive in Autopilot only on the highway, not in cities. And of course Autopilot is available only to those who actually own a Tesla.)

We got a sneak preview of Uber's self-driving cars hitting Pittsburgh's roads. Here's what it was like:

To try the cars, we lined up at Uber's Advanced Technologies Center in the Strip District of Pittsburgh, a small neighborhood on the Allegheny River with nearby warehouses. The ATC is tucked under an overpass for a freight train, keeping it secluded.

The ATC itself is sleek and modern-looking, featuring floor-length windows and giant wooden staircases. The ground floor has tables that can be converted into a dining area as well as several seating areas for relaxing.

Once we got inside we got some up-close views of the first and second editions of Uber's self-driving car. Here we see the first edition, a Ford Fusion with a giant retrofitted roof rack filled with autonomous car tech.

Uber is letting people experience its self-driving cars for the first time starting Wednesday.

The popular ride-hailing service is letting a select few people hail a self-driving car as part of a pilot in Pittsburgh. The cars can drive only in certain locations, including Pittsburgh's downtown and Shadyside neighborhood. Those taking rides through the pilot can ride free for now, but an Uber representative said that may change.

Uber let us get behind the wheel and experience what it's like to monitor a giant robot on wheels, but not everything went according to plan.

First, a brief introduction to Uber's self-driving car: a Ford Fusion retrofitted with driverless tech. The car has a massive, spinning lidar on top and 20 cameras. That doesn't even factor in the several radar and lidar modules on the side and GPS units helping the car drive safely.

Lidar is an acronym for light-sensing radar, a remote-sensing technology that uses lasers to map out the world around the car so it can "see" obstacles.

That lidar on top is exceptionally powerful. Eric Meyhofer, the engineering lead for the self-driving-car project, says it's capable of firing 1.4 million laser points per second to build a 3D view of the car's surroundings. A camera under the giant lidar machinery transforms that black-and-white 3D view into color so it can sense things like traffic-light changes.

But that doesn't mean the car is ready to go out in the world all on its own. We've already heard that Uber's self-driving cars struggle with bridges because there aren't enough environmental cues for the car to figure out where it is.
