The company debuted its autonomous ride-hailing service Sunday. The limited program is invite-only and uses around 20 cars—signs that Tesla has a long way to go to catch up to its robotaxi rivals.

Texas enacts legislation requiring a permit to operate self-driving vehicles just before Tesla's planned launch of a robotaxi trial.

The vehicles will have safety monitors and may not operate in bad weather, making them more restricted than the fully autonomous vehicles promised by Elon Musk.
