I watched a BMW 330ci this morning going through a merge and rotary area. I'm in the left lane, figuring the right is about to bottle up, realize it won't, but the BMW is clearly passing me on the right, so I wait until he's by. Go through the curve, into the merge area, there aren't a lot of cars coming up the ramp, and they don't have right of way anyways. He blows through there, changes over to the left lane... sorta. He ends up cutting through the middle between the two lanes, between a bus and an SUV, creating a never before seen (by me) three lane entrance to the rotary.
Was it a dick move? Maybe. Was it illegal driving? Certainly. Was it skillful maneuvering? Oh, yes.
