Are you serious? They pass on the on/off ramps?
Yep. Not the ramps themselves, but the lane leading to the offramp, or the merge-in lane from an on-ramp. Why let all of that lane space go to waste, right? It's very common to see cars pull out of line to go into the on/off lane, race to the end of the lane, and then turn their left-turn signal on as if it suddenly dawned on them that the lane was ending.
Not only seriously annoying those of us they're trying to pass, but frequently blocking the way of people legitimately entering or exiting the road.
