I guess once you experience a car crash, that perception is changed. When a drunk driver hit me head on and put me in the hospital clinging for life, I'll never forget the moments after the crash. The smell of burnt tires, metal and pavement. The moments when I accepted I was dying and would likely be dead. It stays with you forever. And when you have friends that get their bodies torn in half because the front car smashes into them, you don't forget that either.
Yeah I'm appealing to emotion here. But my point is, so is thinking about how horrifying a plane crash is. Fact still is, more people die daily from car crashes. You are more likely to know people that die from cars than planes. And you yourself are more likely to die from a car crash. And car crashes are violent and horrifying too. It all sucks, and it often deprives person of any control.
