I think many people assess risk differently when they are passive vs. active participants. When you are the driver of a car, you tell yourself that you can avoid any possible accident and it's only "other people" that will be part of those unfortunate 30,000 deaths a year. When you are a passive participant you lose that sense of control and all of a sudden feel yourself to be more at risk. That's a big reason why so many people fear air travel more than driving their car. That said, I hope we find a way past this irrationality. I look forward to a future of fully autonomous vehicles.
