Google’s plan to test a fleet of totally autonomous, self-driving cars hit a snag recently thanks to new regulations from California’s Department of Motor Vehicles.

Taking effect on September 16 and covering all cars tested on public roads, the new rules require that autonomous cars have a test driver who is either “in immediate physical control of the vehicle” or “capable of taking over immediate physical control.” According to Benard Soriano, one of the officials developing the rules, that means the car must have a steering wheel and brake and accelerator pedals, the Wall Street Journal reports.

Unfortunately for Google, its newly debuted self-driving car has none of these. The Mountain View company thus faced the dilemma of either restricting its tests to private roads, or trying to conduct the tests out of state. Apparently dissatisfied with either option, Google has announced it is complying with the rule, and will add a temporary steering wheel and pedal system for its drivers to use during testing.

“With these additions, our safety drivers can test the self-driving features, while having the ability to take control of the vehicle if necessary,” Google spokeswoman Courtney Hohne told the Wall Street Journal.

The whole kerfuffle demonstrates the uneasiness of regulators with the concept of self-driving cars, and lengths Google may have to go to bring them to the public.

“We wanted to take baby steps in terms of testing and how technology is rolled out so we are capable of handling it and Californians accept it,” Soriano told the Journal.
