That's my usual m.o. which can be surprisingly infuriating to people. Waving at them like a long lost friend to that idiot behind you who's riding your ass, then slowing down like you're ready to stop and catch up with an old friend tends to drive them batty.
It's also usually effective to just slam on the breaks when the guy behind you is riding your ass, flashing their lights for you to give way, and doing this when you are already speeding in the fast lane and there is nowhere else to go. I call that entitlement and feel like they're entitled to a break check. The nicer the car, the more sure you can be that they'll make it a point to avoid hitting you.
But, when they finally get around you, you can count on a big old flip of the bird!
