I saw a Waymo with safety driver driving around Boston a few weeks back. The concerning thing was just how much it backed up traffic getting off the freeway because they're not allowed to go any faster than the posted speed limit.
"Car obeys the speed limit, drivers lucid with rage" definitely sounds like my memories of Boston.
Presumably Tesla will not make this decision, it will be interesting to see how much consumers value faster ride times if Tesla FSD ever get their shit together
