I can sympathise with you on this. Touch wood, I've not had a major incident for years, but on my daily commute I do sometimes see red when a car tries to take me out intentionally. I use the word intentionally becauses everyone makes mistakes/can't see you fully, but I once had a guy look me in the face as I rode past and then proceed to use his car to bully me accross the road. I banged on his window and said "what the £$%% are you doing" he just smiled at me and said "sorry, sorry". For a split second I nearly considered taking his bumper off with my hardened shoes and adrenaline, but I managed to tame my Chimp brain (Ive read the book mentioned above) and ride off saying "thanks for that mate!"
In hindsight, I could have ended up in a police station rather than eating my diner that evening and the driver would have played the "I didn't see him card". No winners overall!
