There was a story about a Tesla's radar being blocked by a moth, that smashed to its front. A fully autonomous vehicle would have had to stop and wait for someone to come by and clean the radar. Or there need to be lots of additional minor repair gadgets added to the car to clean sensors in case of dirt.

There are already lots of failure modes that require a tow truck to rescue a human-driven car. I bet the reduction in human-caused accidents (sleepy, drunk, distracted driver) will more than make up for weird new failure modes like sensor-splats.
