... are they as angry in all other parts of their life?
I've just had an incident where a man in a car got so upset at me not letting him out past a parked car that he blared the horn, wound down the window, shouted at me and then drove off flipping the bird... after being annoyed and a bit shaken, I found myself feeling very sorry for whoever has to live with him. It got me wondering; are the angry men and women on the roads the same ones we read about here who make their other half's lives miserable, or are they really lovely people who should just never be allowed behind the wheel?
Or if you're a total dickhead on the roads, are you also a bad tempered cow-bag at home?
