Gosh. That's tough to handle.
I used to commute to work-3 hrs per day in LA traffic.
When I'd get off freeway in heavy traffic I'd be scared of getting car- jacked.
But only once drove recklessly. I was manic and drunk. Put my foot down on gas and took car as fast as it would go. I'm really lucky nothing bad happened .
Sorry you feel such rage at others. Is it something your Theripist could work thru with you.
