Not if I have anything to say about it. I usually ride the bumper of the person in front of me so close that the "merger" doesn't get a chance to get in. Otherwise, like Kevin, I'll actually pull over a bit so that they can't get around the lane to the outside of me.

and you'll watch them sneak in front of someone ahead of you. and while you're half in the lane, they'll still go around you.
I don't think we're thinking about the same type of scenario. This is what I mean. No love for I-won't-merge-like-I'm-supposed-to guy:

ahh, from a merging lane into a driving lane. not from a driving lane into a driving lane. either way, unless there's a concrete median.....they might drive on the shoulder to get around you.
