That seems an unrealistic bar especially as a hypothetical self-driving vehicle will be co-existing with human-driven cars even on main roads for the foreseeable future. Furthermore, airliners are flown by a pair of trained professionals, within an air traffic control system that minimizes their exposure to most serious threats, and are mostly (some bird strikes, sensor failures, etc. notwithstanding) flying under conditions that are fairly predictable. OTOH, I doubt a self-driving vehicle will be all that better at dealing with a deer jumping out in front of a car, unexpected road debris, or black ice all that much better than an alert human driver. (And possibly worse given that a human driver may pick up on certain cues that an automated system might not.)
Something here is unrealistic, that's the point. I'm not so sure it's the reliability threshold for self-driving cars though. I'm more amazed at our continuing acceptance of the risks in driving. Having two pilots, air traffic control, maintenance standards, etc, are all regulation driven. Why do we have all those regulations if we're willing to accept 1000x worse in cars with much more lax regulation?

I'd expect the opposite actually. Humans are incredibly slow reacting in the best of circumstances and they often drive distracted. They also suck at reacting even when they do which is why we now have automatic systems to reinforce braking in presumed emergencies as humans don't consistently apply full brakes in emergency situations. Collision avoidance in a few milliseconds with reliable reactions should make quite a few of those scenarios much better.

I think it boils down to "because we can and still have a viable commercial airline industry." (And general aviation is much riskier than commercial airlines.) Whereas were we to vastly increase the training, maintenance schedules, monitoring of driver alertness, and requirements to have all the latest safety features, you're probably effectively eliminating driving for most people who can't just hire a professional driver/car.
For many things, we accept that we could make things safer if we wanted to. But were we to do so, we'd effectively be banning the activity or at least severely restricting it. (Which is probably one reason why we don't really have flying cars.)
I agree with most of this, except for the unexpected rapid-response examples you list - I would expect an autonomous collision-avoidance system to react faster than a human being when faced with a deer in the road or someone running a light (otherwise - it's not a very good collision avoidance system!)
It can react faster to an object. But, under at least some circumstances, a human might recognize potentially questionable road conditions in a way that an autonomous vehicle would not. (Of course, presumably the human could also tell the autonomous vehicle to slow down.) And I've definitely seen animals at the side of the road looking they may be inclined to run out.
