Elon Musk's Tesla has applied to test and eventually deploy its Robotaxi vehicles in Phoenix, Arizona, following in the footsteps of market leader Waymo.

The three autonomous driving experts told Business Insider about how they think the launch went, and what may have prompted some issue.

It's too early to definitely answer whether or not Tesla's Robotaxi service is safe, but it's clear that riders have experienced some mishaps first-hand.

Tesla is expanding its initial small Robotaxi offering in Austin, Texas, and planning to introduce Robotaxi services in California and Arizona. The company

NHTSA pressed Tesla for more information about robotaxi incidents caught on camera and shared widely on social media.

Since Tesla's recent launch of its robotaxi service in Austin, videos have emerged showing driving problems including speeding, sudden braking and driving over a curb.

Musk for years has failed to deliver on promises that self-driving Teslas are just around the corner. Tesla rolled out the service for a flat fee of $4.20 to a limited number of handpicked riders. The service is not available to the broader public and the robotaxis operate in a limited area, and avoid difficult intersections and bad weather.
