Autonomous
Vehicles) Elon Musk's proposed robotaxi service that uses the vehicles of Tesla owners when not being driven. Competing directly with Uber and Lyft, Tesla's SAV service is designed to use the vehicle's autonomous driving mode that does not require a human driver at the wheel. When Tesla owners park their cars and put them in SAV mode, the vehicles become available for taxi service. During the time they are not needed, owners derive income. See
