Google has unveiled a prototype of its proposed driverless car, the Associated Press reports.
The car has no steering wheel, brakes or gas pedals, according to the report.
Instead, the vehicles will be operated using simple “stop” and “go” buttons.
The company is waiting for state and federal officials to write regulations for driverless automobiles before fully moving ahead with the new technology.
Driverless cars have presented a challenge to existing liability rules for insuring cars and determining responsibility for potential accidents.
Lawmakers have expressed a mix of excitement and trepidation at the thought of computer-powered cars being operated on U.S. roads.
