DETROIT – General Motors Co. is seeking U.S. government approval to include a fully autonomous car -- one without a steering wheel, brake pedal or accelerator pedal -- in its first commercial ride-sharing fleet in 2019, executives said. For passengers who cannot open doors, the Cruise AV -- a rebranded version of GM's Chevrolet Bolt EV -- has even been designed to perform that task. It will have other accommodations for hearing and visually impaired customers. This will be one of the first self-driving vehicles in commercial passenger service and among the first to do away with manual controls for steering, brakes and throttle. What is the driver's seat in the Bolt EV will become the front left passenger seat in the Cruise AV, GM said.
