No, telling, I fear heights, and HATE to drive over long spanned bridges get this weird sinking feeling in the pit of my stomach, BUT do it because I must to arrive at where I am going.
I too, fear heights and bridges of any sort. I wouldn't get out of a car while on a bridge, unless the car was on fire or I had a gun to my head.
To get out to inspect a rented car for damage? No Way!
Or if he was in the midst of a seizure, I would think it would be difficult to get out of the car, but what do I know-not much!
