I know that some of my major triggers are being in drive throughs, with no way out. Roads with no u turns, stop lights with no easy way to "escape" the red light (say there is traffic on both sides). I also don't even like the feeling of being in the car. I think this fear of driving took over after I got rid of my fear of something else. I find I seem to replace fears with other ones. For example, I used to be terrified of restaurants. My anxiety on that has decreased, I'll go to restaurants now. I'll even sit on the inside of the booth, when I used to have to sit on the edge or be close to a door. As that subsided, my anxiety with driving went up.
