While the causes of road damage you cite are certainly more salient, they're not actually very common causes of accidents. Much more common is driver inattention or driver error. Inattention is directly addressed by self driving cars, as they are always paying attention. Error should be lower as well. As long as it can detect where another car is and it's approximate velocity, it should be able to avoid that car. Computers have far better reaction times than humans.
