I think not, since that's the worst thing for a service industry, to have gigantic sunk costs. If you look at Uber's model now, they pay labor only, and have no liability for the hardware, or for insurance costs and repairs. Even assuming that the AIs can perfectly avoid inducing an accident, it just means that everyone around is a worse driver, so there will still be accidents, but now, you're talking about totaling a car that has $25k of additional hardware and the liability of any secondary incurred insurance risks. Uber had to settle with that pedestrian's family; had that been a human driver, Uber would have had washed their hands of the whole incident.
