All my line of argument is trying to adress is how long until self driving cars are 'ready' which directly relates to how capable they are today. The data I looked at suggested somewhere above 'drunk driver' but below 'school buss driver'. That seems like an extreme range, but they are each human levels of competence. Which is different than they are being portrayed and IMO a sign they are very close to ready.
While the points you bring up are meaningful, we let people drive without those safty features. So, in terms of policy it seems like an ever higher bar, as for example automated breaking systems and lane following raise the bar above human competence, but again are not being installed on older cars.
Which... doesn't really make sense. The safety features are part of the package. You can't get the dangerous part without them.
No cars are sold with a big blob of naked unprotected lithium ion cells. And no cars are sold with autopilot but not high-end crash protection.
A feature being dangerous in isolation is not enough to show that it lacks net benefit.
If (and that’s likely) other features than Autopilot contribute to Teslas killing and injuring fewer people, we must compensate for them to judge whether Autopilot is a net benefit.
