Google car sans steering wheel

Sergey Brin, co-founder of the technology titan, told a Southern California tech conference on Tuesday evening that Google will make 100 prototype cars that drive themselves and therefore do not need a wheel. Or brake and gas pedals.

Instead, there are buttons for go and stop.

A combination of sensors and computing power takes the driving from there.

To date, Google has driven hundreds of thousands of miles on public roads with Lexus SUVs and Toyota Priuses outfitted with the special equipment.
