I hear what you are saying edge, I used to do that, but I'm still suffering a tad of PTSD from doing just that. It was a really horrible experience. A car crawling along an isolated road about a year back, hogging the broken white lines so I couldn't pass, doing way, way below the speed limit, really crawling. I beep for it to pull over and let me pass; they stopped the car in the middle of the road and stupidly so did I not thinking anything was up, just some asshole about to moan about being beeped. Actually it turned out to be four assholes getting out to have a quiet word with me via baseball bats and claw hammers - real scumbags and I mean scum of the earth, thankfully I had the survival instinct to reverse back then drive at them (I was too scared to give a damn if I drove over them) and they scattered, and I, with my heart coming out my throat drove down that road like a bat out of hell until I got to an intersection leading to a populated main road was able to mingle in with traffic. If I hadn't reacted like that, I'm sure I'd have been killed. I have absolutely no doubt. I still shudder when I think about that. I don't think I've beeped my horn since.
