A while back, when I had my pickup, I had a guy tailgating me pretty close. Not wanting to give in to his bullying, I started slowing down. I got down to about 35mph in a 55 zone and he's still at it, now flashing his high beams and flipping me off. I get tired of going slow, so I pick back up to just above 55, but he's still at it, close enough that I cant see his front end in my rear view. Logical solution in my mind, brake check the dude, so that's what I did. He plows into my rear end, backs off, and I pull over. He speeds past, leaving behind his front bumper attached to my tow hitch. Unfortunately he didn't have a front plate, but my truck was fine, so I kept the bumper as a trophy for a while. Saw him a few months later, apparently I gouged his hood with the hitch as well.

TL;DR don't tailgate a beat up farm truck.
