Nash, glad you're alright. That could easily have been fatal.
For people who do most of their riding in a rural environment, the key to heavy-traffic urban highway safety is this: get in the left lane, and keep yourself as conspicous as possible by keeping to the right side of the lane. It is extremely difficult to avoid someone who just aims at you, like Nash did, but by riding the left lane you only have to worry about attack from the from, the back, and the right, and by keeping to the right side, you are aeasier for cars in the next lane to see. Should they try to take you out, you still have half a lane to work with.
Like Chris said, mirrors come easy. Could have been worse.
