I do some dissociating while driving as well, and just yesterday was in a very near scrape that could have been very serious, and sure the other driver was swearing the Hell out at me!
For me, when I drive, which I must do, I try to focus all the time on my surroundings, aware of the rear mirrors to right and left, my speed, forcing myself to stay focused on all the factors of safety. I am supposed to drive 3.5 hours to my daughter's house in the next week, and have realized lately that I don't enjoy driving because it is much work for me, remaining focused....but!!! I must! If you are going to drive, Inny...try practicing as I do on remaining focused on all the factors.
