"Oh Shit" moments...

I think it's because they haven't got the same surge of adrenaline that you just did. You, hopped up on adrenaline and rage, understandably raise your voice a bit and get a little confrontational, whereas the person who almost killed you isn't hopped up on anything, but they have just made a mistake and now to make matters worse somebody is shouting at them for it. Some of them get defensive and confrontational in return, some of them burst into tears.

Adrenaline and rage, my favourite combination. You feel so alive, then you feel exactly like a quivering leaf.

She will have learned though. Won't be doing it again in a hurry.

Well, let's hope not! Someone I know once accidentally doored someone (and it was a bit of a freak accident) and now will barely open car doors and does a weird slither out of any vehicle to avoid opening the door more than about 10cm.
