That's one reason I avoid public transit in San Francisco. However, it hasn't been a problem in my use of taxis, rental cars, Uber, or Lyft, so I presume it won't be a problem with autonomous cars. They'll either drive themselves to the car wash when someone has an accident (spills, pees, vomits), or if for some reason a "wet" car arrives, then you'll report it, and get the next one.
