Lyft is upping its game with a fleet of self-driving cars that will hit the streets of San Francisco.

California’s Bay Area is the hotbed of autonomous driving technology and Uber’s biggest competitor is hoping to get ahead with a test of vehicles that will give passengers a ride without a driver. A select group of people will get a free autonomous ride from Lyft.

There will technically be a driver on the front in order to comply with California law as we have yet to fully enter a world where it is acceptable to ride a car with no one behind the wheel. The move is in partnership with Drive.ai.

The two companies have yet to reveal when the pilot program will kick off, how long it will run for, how riders will be selected or what place will be chosen for the tests. Lyft hopes the move will help it determine what the future of transportation services will look like, potentially cutting costs by not paying drivers.

“We really want to understand, what are all the pieces that need to come into place?” says Taggart Matthiesen, Lyft’s product chief.

Meanwhile, Carol Reiley, Driver.ai co-founder and president, said the company’s excited to use Lyft’s network of customers. Driver.ai is a self-driving startup that has been around for two years and this will be the company’s first opportunity to test its technology on a wider scale.

Other companies testing self-driving technology include Samsung, Apple and Intel.
