@susankayequinn looks like there's some "tuning" going on https://www.sfchronicle.com/sf/article/waymo-robotaxis-driving-like-humans-20354066.php, which they will hopefully get in trouble for.
As for the liability, Uber has a similarly effective solution that doesn't require $30b (and counting) of investment: it stops with the driver-contractor. They do provide additional insurance, but they usually can't be sued themselves AFAICT.
