In Car Entertainment

This is something that I do from time to time when I'm feeling horny whilst driving. First of all I adjust my rear view mirror so that someone from behind the car can see my crutch area. Then having dropped my trousers to my knees or removing them completely and put on a condom, I continue to drive whilst rubbing my cock, hoping that a woman driver, preferably mature and alone, will see me from behind in my mirror. I've not had any reaction so far but some incredible orgasms when I think someone may be looking.

Has anyone else tried something similar. Ladies, what would your reaction be if you saw this?
