Nearly half of the Waymo crashes reported to police in metro Phoenix were hit-and-runs.
Accounting for miles driven, Waymos were involved in police-reported hit-and-runs at 2.4 times the rate of drivers in Maricopa County.
There were 88 police-reported crashes involving Waymo vehicles from Sept. 1, 2020, through Dec. 31, 2024.
The company said rear-end crashes are the most common type of crash for both human and autonomous drivers.
Arizona law requires drivers who hit an unattended vehicle to locate the owner or leave their contact information.
