A first public test of robotaxis by Tesla in Austin, Texas led to multiple traffic problems and driving issues, videos from company-selected riders showed over the first few days.

Tesla launched its robotaxi service in Austin on Sunday as its Model Y vehicles drove around a select batch of riders who gave rave reviews about smooth, convenient rides that were available for the cheap price of $4.

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.
