Though many other details are still getting worked out, Lyft riders will be able to opt out of getting picked up by a self-driving car when they hail a ride through the app, according to the report. Lyft will also have drivers in the cars at first to ease safety concerns, but the company expects to eventually phase them out. The companies also plan to eventually make Chevy Bolt cars available for Lyft drivers. At the moment, Lyft drivers can rent out Chevy Equinox cars from a GM-owned and operated hub in Chicago, though that program will expand to more cities and shift to mostly Bolt cars. "GM continues to make progress on our previously announced plans related to an integrated on-demand autonomous network with Lyft. Similarly, we have said the Chevrolet Bolt EV is the ideal platform for ride-sharing solutions," a GM spokesman told Fortune. "We have nothing specific to announce in relation to potential rollout of vehicles and technologies at this time," he added.
