It’s not exactly public transportation, but developers at Google, Inc. are designing technology that allows cars to drive themselves. Democratic State Senator Alex Padilla is so enamored with the plans that he let a Google-designed self-driving Toyota Prius give him a lift to Sacramento to hold a news conference about it.
As reported by the Environment News Service, the reason for the occasion was Padilla’s announcement of his legislation, Senate Bill 1298, which would instruct the California Highway Patrol to start “developing guidelines” around testing and ultimately unleashing self-driving vehicles on California roads.
The Google system utilizes a “laser range finder” on the car's roof, and no less than four radars mounted on the front and back bumpers. A camera keeps an eye on traffic lights.
