Recently Google surprised everyone by announcing the self operating car. Google recently completed 14000 miles of testing. According to Google
So we have developed technology for cars that can drive themselves. Our automated cars, manned by trained operators, just drove from our Mountain View campus to our Santa Monica office and on to Hollywood Boulevard. They’ve driven down Lombard Street, crossed the Golden Gate bridge, navigated the Pacific Coast Highway, and even made it all the way around Lake Tahoe. All in all, our self-driving cars have logged over 140,000 miles. We think this is a first in robotics research.
Folks at Geekculutre made a nice comics describing the results if tech companies such as Facebook, Linux, Microsoft, Yahoo start making their own car. Check it out.
