From a legal standpoint, it is ALWAYS the responsibility of a person driving behind a vehicle to leave a safe distance between themselves and the car in front of them. On the flip side, to drive defensively also means it is the responsibility of the lead driver to conduct themselves in a manner that does not put others in harms way (including themselves).

Don't get me wrong, I would have probably done the same thing myself. But what about the minivan full of kids that could have potentially been behind the Bimmer and got into an accident as a result. I consider both drivers aggressive in this circumstance. Now let me get off of my high horse and say...fuck the bimmer driver. He should have been paying more attention and left more distance. An expensive lesson to learn...
