While the initial testing will use Tesla's own fleet of cars, regular customers may be able to add their cars to the ride-hailing fleet next year, Musk says.

The robotaxi service Musk said will launch in June will likely be distinct from the purpose-built “Cybercab” vehicles that it touted at a splashy LA event in October. Tesla said at the time that it would aim to start manufacturing its Cybercab—which won’t have a steering wheel or pedals—sometime before 2027.
