I hate BMWs

Today's loser car is a BMW. I was driving down the street in the right lane when I saw a man walking in the street. I thought the left lane would be a better bet at about the same time the BMW behind me thought the left lane would be a good lane to pass me. She honked, and I got over as soon as I got by the pedestrian (I think the sidewalk was still covered with snow). So far, that was pretty normal. But then the BMW just started weaving from right to left lane trying to pass everyone and not getting very far. The roads were pretty clear, but this driving was dangerous in any condition.
