The onward march (or rather drive) of autonomous vehicles shows no signs of slowing down, with proposals under consideration in California to allow cars without any human passengers or drivers on to public roads for the first time.

Dozens of companies are busy testing their self-driving tech in the Sunshine State, which has regulations favorable to the fledgling industry. But up until now, vehicles haven't been able to take to the streets unless they had a back-up human driver on board, ready to take over should something go wrong.
