Initially, the pilot will involve a small set of passengers who will opt in to this program, Taggart Matthiesen, senior director of product of Lyft, told The Verge. He did not provide a specific number of vehicles or participants, but noted the self-driving car will have a Drive.ai safety driver behind the wheel to take over in case the artificial intelligence controlling the car fails, and of course, to meet California regulations.

Once a ride is requested, Drive.ai’s software will evaluate whether or not the route is feasible, said Carol Reiley, co-founder and president of Drive.ai. This may be a route that has been pre-selected, Reiley said, adding that the company’s self-driving technology can handle rainy and nighttime conditions.
