Fly by pants
Fly by wire aircraft aren't whizzing past dozens of other fly by wire aircraft less than half a metre away every minute or so. It's a very different situation and not very comparable in safety terms. The reason I'm far more willing to trust myself to other meat packets in control is based on experience. I'm sure if you drive all day most days you are far more likely to be the victim of a mistake by another driver, but if you only drive occasionally on mostly familiar routes your chances of having an accident are much reduced. The problem with this self-driving deal is that it is far more random and you can't really calculate your risk. I'd be terrified to drive on a road full of self driving cars at this point in time.
