This drives me nuts, I literally have road rage every day from this happening on my drive in. Rockville Pike and some other street I couldn't tell you has cars merging at the very last second all the time. They fly by you on the right and then cut you off at the last second.
I'm to the point now were I ride the bumper of the car in front of me so they can't get in. I get so angry!
Well, I feel slightly better after watching this. It happened on a freeway exit near Montreal last month, and this guy's dashcam captured it on video.Guy merges last second and a police trap at that exit ended up spotting him and had him pull over!
