A Los Angeles tech entrepreneur found himself trapped in a self-driving taxi last month on his way to the airport, with the car repeatedly circling around a parking lot. Mike Johns posted a video on LinkedIn in which he was headed to Sky Harbor International Airport in Phoenix.

A video posted by a Waymo passenger shows the autonomous car he rode in going in circles in an Arizona parking lot while he tried to get to the airport.

Waymo, which is owned by Google’s parent company Alphabet, told Gizmodo the rider wasn’t charged for his trip and has attempted to contact Johns but they haven’t connected yet. Waymo also emphasizes the circling lasted about five minutes. Johns told ABC15 Arizona that he was frustrated by the experience and “It’s like people are the experiment.”

Last month, a Waymo rider was left reeling after his self-driving rideshare drove in circles on its way to the Phoenix airport.

Mike Johns ordered a Waymo, the self-driving rideshare service from Google, but found himself in a malfunctioning car driving in a never-ending loop around the parking lot he was in.

A man in a Waymo driverless car got more than he expected when the vehicle he was in kept going in circles and wouldn't stop.
