Wow. The poster Chap who saved a crash didn't really act out of turn. He was upset at apparent poor signalling. The poster who retorted with nastiness was nasty. She/ he resorted to a personal attack. Makes me think maybe she/he was in the wrong and used the old defence mechanism of attack. Anyway. There are not two sides to a story there are 3 his, hers and the truth.
This driver almost caused a crash by narrowly missing a car which had a child in it. Her license should be suspended immediately!
