No driver's licenses by 2040?[ Tue, 18 Sep 2012 10:02:02 EDT ]The timeline for autonomous cars hitting the road en masse keeps getting closer. GM's Cadillac division expects to produce partially autonomous cars at a large scale by 2015, and the automaker also predicts it will have fully autonomous cars available by the end of the decade. Audi and BMW have also shown self-driving car concepts, with the former working with Stanford to pilot a modified TT up Pikes Peak. Meanwhile, Google is ripping along at its own rapid pace with a fleet of fully autonomous Toyota Prius hybrids that have logged over 300,000 miles. And the company has pushed through legislation that legalizes self-driving cars in Nevada. California is close behind, and Google has also been busy lobbying joyriding lawmakers in Washington, D.C.
