Arguably the problem with Tesla self-driving is that it's stuck in an uncanny valley of performance where it's worse than better performing systems but also worse from a user experience perspective than even less capable systems. Less capable driver assistance type systems might help the driver out (e.g. adaptive cruise control), but leave no doubt that the human is still driving. Tesla though goes far enough that it takes over driving from the human but it isn't reliable enough that the human can stop paying attention and be ready to take over at a moment's notice. This seems like the worst of all possible worlds since you are both disengaged by having to maintain alertness. Autopilots in airplanes are much the same way, pilots can't just turn it on and take a nap. But the difference is that nothing an autopilot is going to do will instantly crash the plane, while Tesla screwing up will require split second reactions from the driver to correct for. I feel like the real answer to your question is that having reasonable confidence in self-driving cars beyond "driver assistance" type features will ultimately require a car that will literally get from A to B reliably even if you're taking a nap. Anything close to that but not quite there is in my mind almost worse than something more basic.
