Not good enough. I think Tesla have a lot to answer for here. They are pushing the limits of a technology which Google has said, "needs to be 100% autonomous". No steering wheel. Tesla knows this, but branded their car as 'auto-pilot' anyway. When it became clear from early youtube videos that people were not using the technology 'correctly' Tesla did nothing more than issuing a statement. They should be considering…
Paraphrasing from JFK: We choose to make auto-driving cars, not because it is easy, but because it is hard.
There will be casulties along the way. Deaths are not a reason to stifle development. If we'd done that, we'd never have spaceflight or Vaccines (or Nuclear Weapons for that matter...) .
