Lyft (LYFT) now looks more compelling to investors after Tesla’s (TSLA) subdued robotaxi launch in Austin because the latter’s relatively weak debut eases worries about the potential for disruption in the ride-hailing industry by robotaxis.

CNBC went to Austin, Texas, to check out the supervised, invitation-only launch of no more than 20 of Tesla‘s robotaxis. CEO Elon Musk once promised Tesla would be able to drive themselves and owners would be able to rent out their vehicles for rideshare.

Onboard helpers, bad-weather suspensions, but no crashes. WIRED asked experts to grade Tesla’s Austin autonomous taxi service—and, crucially, how to know if the system is safe.

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