If you routinely hit other objects, even at 1-4 mph, you are not a good driver.

The average driver also likely hits objects at 1-4 mph at more than 4x the rate they hit things at a severity high enough to generate a police report.

The data is inconclusive on whether Tesla robotaxi is worse than the average driver.

Unlike humans, Waymo does report 1-4 mph collisions. The data is very conclusive that Robotaxi is significantly worse than Waymo.
