There’s a lot of good data presented in that, but I think they make a false comparison of conventional vehicles accidents per mile to AVs. They are comparing all miles driven everywhere for conventional cars. Versus where AVs are being tested and driven and California only reporting, which appears to be mostly highly challenging city environments.
Additionally, they are reporting events with no damage and minor damage. What percent of vehicle incidents nationwide go unreported, because there is no damage or only minor damage and people don’t want to get the police or insurance involved?
