I'm just throwing something at the wall here: Just start with a purely assistive package like most big manufacturers have. Let buyers opt-in to a test program (giving them, say, a 3% reduction on the list price), where all their inputs and outputs are recorded and sent to the manufacturer. Manufacturer can now assimilate that data into a model of car and road and test their fully autonomous software on that model and search for situations where the software gave much different input compared to the human driver. Check these situations in an automated way and/or manually to see whether it's a software error or improvement. IMO this approach would have had a high chance to find the bugs that caused the two recent fatalities, as I'm convinced that most human drivers would have done better there. After years of doing this (which seems to be close to what Waymo is doing if I understand correctly), the autonmous software should be way better than what is being pushed out now by Tesla and Uber (and probably a bunch of others).
