Reinventing the car isn't easy. After all, we still use four wheels and internal combustion like we did more than a century ago. That doesn't stop people from trying though, and more often than not those ideas don't work out.

10.) The Dymaxion car

We love Buckminster Fuller's crazy invention, and many out there feel the same way. Still, there's no denying that DennyCrane is also right:

Touted for being roomy, efficient, and safe, one of those turned out to be quite wrong as a driver at the World's Fair was killed when it rolled, despite wearing a seat belt (A feature not even standard at the time), and seriously injuring two passengers when the roof collapsed completely.

It rolled because the steering was not just bad, but the problem was inherent to the design. Oh, and it could only go 75% as fast as the top speed they claimed it could reach.

That was the safety feature, duh!

9.) The Aurora ESV

If this isn't the ugliest car in the world, I don't know what is. Built in 1957 by an American priest on a 1953 Buick chassis, it had a wooden frame, fiberglass body and plastic windows. It didn't work.

Luckily, the experimental safety vehicle got restored in 2005 so we can all enjoy it a bit longer.

8.) Aptera 2e

Big claims, big failure, tax money not well spent. Still, at least they never give up.

7.) Flying cars

Let's face it: flying cars like the Terrafugia are not much more than planes with bigger wheels. Cars and planes just shouldn't mix. Except when it comes to Saab Aeros.

6.) Ford Gyron

Ford had a bunch of insane ideas throughout the fifties, but the Gyron is actually from 1961. Fl1ngstam is here to tell us what was wrong with it:

The 2-wheeled Ford Gyron of 1961 was a cool idea, with it's gyroscopic balance controls, etc (possibly made of some form of voodoo-vaporware), but look at it.

The overhangs are ludicrous, the huge perspex top would toast the occupants as soon as the sun came out, and the merest bump from a passing motorcycle would send you scraping along the asphalt on your ear.

5.) Any hydrogen car

The first hydrogen fuel cell powered prototype was finished by a gentleman by the name of Bacon in 1959. We're in 2013, many millions have been spent on research and development by basically all major manufacturers, but it feels like Mr. Scorpio is right once again.

4.) GM's Firebird Concepts

Putting wheels on a jet engine. GM got confused and tried to sell speed record cars as the future of mobility.

3.) Genepass H2O

This water-powered plastic wonder ended up as an underpowered electric car marketed in the UK. Terrible in every way.

2.) The Curtiss-Wright Aircar

This hovercraft wasn't a Ford but a concept made by Curtiss Wright, and was doomed from the start.

1.) The Sir Vival

You might think I'm joking, but this thing exists, even today. Thank Jonee for spreading the horror:

The Sir Vival has to be one of the most bizarre and hideous attempts at a car of the future. The two part design was supposed to keep passengers safe in a crash. It was heavily modified '48 Hudson that, unsurprisingly, handled like shit and was near impossible to drive. But, like its name, it still lives.
