Not speed/calming humps, but I've noticed over the weekend while traveling though WV,TN,NC, VA several drivers we've been behind, are simply stopping in the middle of the road. There's no stop sign, no stop light, nothing crossed the road etc.. They're stopping because you're (me/us) are following too close.. So just be warned, that if you follow these panicky drivers, be prepared to stop for nothing behind them. They way we look at it, I/we know where we're going.. and apparently they don't or they're texting and can't pull over. In fact several drivers would actually pull over or act like they are turning until we pass then get back on the road.. I wouldn't say we tail gate, but seriously, drive the **** speed limit..
