I think that the answer above is a little harsh, although being a car insurance underwriter, i'm familiar with how many accidents people over 65 cause....and believe me, it's plenty.
Without wishing to sound rude, in relation to the original topic, was this actually a question or just exasperation as he was caught and yet others aren't??
Also, for future reference, if you'd have stopped and got hit from behind, the car who hit you would've been instantly at fault because, even if you brake suddenly, he should be allowing stopping distance and would be liable in the event.
Always handy to know.
