People that pull right out in front of you just to make a turn, when they could’ve waited that extra 1/2 second for you to pass because no one was behind you.
The other side of the coin is the one that races ahead of you in the left lane, suddenly veers in front of you (even though there is no car less than a quarter of a mile behind you), and then abruptly enters an exit ramp saving himself one tenth of second. But you have to slow down to avoid slamming into the moron as he or she slows down to exit.

Meh. You are in Massachusetts. Inevitable. It might even be a law.
