... to save your leg a bit. Roll back the 3 inches and use their car as a nice prop. ;-)

That's a pet peeve of mine: people who have no clue that a stick shift on a steep hill requires a certain amount of rollback room, no matter how good the driver is. I've had people tailgate me up hills on snow-covered roads.

My main defense tactic is to start rolling backwards *before* the ass behind me gets it in his head to cinch up the slack. A few small bebops on the brake remind most people to leave the room. Some people quite satisfyingly freak out when they see the car in front of them rolling backwards without backup lights on...
