Accident are stuffs that cannot be predicted. A bug is something that can be avoided.
As far as I am concerned, 99% of the software industry is not able to write critical software that is able to handle with a correct costs the case of failures and/or "abnormal" behaviors.
Software will fail. It will eventually fail dramatically. And with software it can fail in a reproducible way. Nowadays all experiments are made far from worst case (congestion, interferences, extreme conditions....)
Who is gonna pay for the predictable accidents? And will self driving cars will be better at avoiding accidents than humman given a same operating cost on the long term?
My guess, is : hell no.
