Waymo crashes 80-95% below human drivers — and safety keeps improving over time

A quick analysis of Waymo's published safety data on police-reported crash rates across three cities finds Waymo 80-95% safer than humans depending on the metric — and its crash rate keeps declining over time, meaning today is the worst it will ever be.

The thread also draws pushback: researchers note crashes are only the easiest-to-measure worst outcome (data on stuck cars, blocked emergency vehicles, illegal turns is lacking), and some of the improvement may reflect human drivers becoming more cautious around robot cars — effectively outsourcing safety to humans.
