The olfactory problem with waymos is that if someone gets in one dirty or foul smelling there isn't a driver to kick them out. Waymos are starting to get more ridership and some of those people are going to be absolute pigs. I gave feedback to Waymo about a recent ride where the entire car smelled like a fat, unwashed ass and the best case scenario there is that they took the car out of rotation immediately, the rider right before me left it that way and that the rider will be identified after several instances of those reports. The reality is probably that the car picked up several riders after me until one reported a problem mid-ride.
