Just maybe there was a history between that critter and the driver and the critter wouldn't take warning and got it's comeuppance.

Who knows. Saw a family of ducks do somethig similar at a very busy intersection. Some idiot woman in a distant lane stopped her car and attempted to stand there and direct the ducks. I kept waiting for a big crash (stupidly but unable to move, could of got us all killed). The ducks made it. It was unbelievable.
