Looking for opinions. So I am driving to work at 5:30 this morning on snow and ice covered roads of WV when a black Prius comes up behind me and rides my bumper for several miles. I am in four wheel drive doing a steady 35 mph with no troubles. Come up on a long straight and the Prius pulls out to pass so I let off the throttle to let him pass figuring at least he won't be on my bumper any longer. He blows the horn as he passes and then the SOB cuts back in too soon and I have to hit the brakes to save my front bumper so then off course my truck is sliding sideways. After my truck recovers I look up the road and see him still fishtailing finally doing a 180 and puts it off in the side ditch. I am usually a very [FONT="]courteous driver and stop to lend a hand when I can but this morning it looked like he was ok so I just kept on driving and blew the horn[/FONT] as I passed to return the favor. After arriving a work starting thinking that I really should have stopped - hindsight is 20/20. Would you have stopped?
