Cars were invented over 50 years ago, back when electronics were just starting to become popular, back then, it would've been impossible for anyone to even imagine a car driving itself. Nowadays, computers are so smart they can drive, there are cars that can actually drive, but I think that's not enough.
I think the real revolution will be when future (flying?) cars are invented, we're gonna need a new infrastructure, one that controls cars, one where cars don't drive, but rather, are driven by a central system.
Have you seen the movie Babylon A.D.? No? OK, imagine cars flying between buildings like you see in sci-fi movies, here's a picture to make your imagination's life easier:
Why let humans drive when computers can do the work? Why risk people's lives by allowing people to drive? People sometimes drive crazy, computers don't! People sometimes get drunk, computers don't!
So if ever someone who reads this blog and designs a future car, please consider this! ;)
