from cnet.com: Google has built a self-driving car from scratch — a vehicle that has no steering wheel or accelerator or brake pedals. A two-seater prototype of the vehicle was unveiled Tuesday by Google CEO Sergey Brin during an onstage interview at the Recode Code Conference in Palos Verdes, Calif. Instead of the car controls indispensable to today’s drivers, Google’s prototype relies on built-in sensors and a software system to safely maneuver the vehicle.
