I can manage cars, but I have a sort of mental block I've had to adopt to stop myself thinking about tires blowing out. It helps that I can't see them.

I generally only ride elevators if it's more floors than I can comfortably climb stairs, and I don't like them. Given the opportunity, I always take the stairs. And I spend a lot of my time on elevators specifically trying not to think about the arrangement of pulleys and cables that's the only thing standing between me and death. Again though, it helps that I can't actually see them.

Airplanes are sort of odd, because they don't much scare me. I think the whole thing is so complex and foreign that I can't get a firm idea of what specifically could fail, so I don't have any specific thing on which to focus the fear. I dunno - I just know that they don't scare me.

Trains are a bit unsettling though, I guess because wheels and rails are something on which I can and thus do focus. It's va fairly distant rhing though, and thinking about it is the exception rather than the rule.

And so on...
