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.

Mike Johns posted a video on LinkedIn in which he was headed to Sky Harbor International Airport in Phoenix. Johns was still able to catch his flight but was left dizzy and frustrated by the experience with the taxi from Waymo, the self-driving car arm of Google’s parent company Alphabet. Waymo said the incident caused a five-minute delay.

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.”
