Got these jerk-offs purposely ONLY using my driveway to turn around. They seem to pull up far farther than a normal driveway turn-around. All of these are to visit a house (crak-house?) 3 doors down. A few times, they've pulled up and sat there like its a visitor for me.
I don't want to do "spikes" just yet, which was my first thought.
EDIT: Sometimes they'll sit there without pulling back out for 30 sec. to 1 minute even. I'll start small and make each booby trap better.
Spike strip will lead to them fire-bombing your house. You need to pick something that gets the desired result but doesn't piss them off too much, or lead back to you.
I would sprinkle about 20 nails in the area. When they leave, go out and see how many are left and pick them up so you don't drive on them yourself.
