Perhaps we will end up with a standardized validation simulation model that autonomous vehicles must pass for licensing. The test suite could grow as more anomalous scenarios are analyzed (ex: acceleration into gore point; white-painted trailer truck turning across divided highway; debris on highway), and it would ensure that any new vehicle on the market or OTA update would meet a minimum of safety. Manufacturers could compete on test suite coverage and acceleration curve stats, and market using rendered video of simulation results showing superhuman skill.
