Yeah, the "cruise control passers". I don't know if they even realize they can accelerate to pass and their cruise control will return them to their previous speed when they're done. Of course, they have only the most peripheral awareness that other cars even exist, so that knowledge probably wouldn't make much difference.

And then there's the opposite problem, which isn't an annoyance so much as a curiosity - the drivers who continually pass you, then fall behind you, then pass you again, etc. This past weekend on the freeway I was cruising in the right lane and in the span of ten miles one car passed me and fell back behind me a half-dozen times. And I had the cruise control set the whole time!

Ah, that reminds me of another behavioral trait, most commonly seen with drivers of expensive "Euro" cars: You pass them because of their slow pace (usually yapping on a cell phone) and when past, they suddenly decide to drive 10-20 mph faster and sit on your bumper, if not to try and pass you back. An ego thing most likely.........

My ex wife had a POS hyundai when they first came out. On trips to vermont, i could do a reasonable speed on flats and downhill, but up the Vermont hills, i'd be down to about 55. I hated it, because I was doing just the annoying behavior you describe.
