Google thinks its self-driving cars will be available to consumers in three to five years, however regulators and the insurance industry aren't so sure it can happen that quickly because sensors would have to react like a human, the cars may have to be licensed rather than the people and insurance companies would have to reassess how to assign fault, plus safety standards would have to be rewritten.
“The improvement can be such that we can make cars that drive safer than people do,” Anthony Levandowski, product manager for Google’s self-driving car technology said. “I can’t tell you you’ll be able to have a Google car in your garage next year. We expect to release the technology in the next five years. In what form it gets released is still to be determined.”
David Strickland, the head of the U.S. National Highway Traffic Safety Administration said “It’s going to make a huge difference in reducing crashes overall,” Stickland said in an interview.
