in the same vein, drivers that pull up to pass you and then just hang there side by side with you...you have your cruise control on so you know that they are the ones slowing down....
and another very dangerous type of driving....going down a four lane.....you're on the right....a car is catching up on the left.....in you lane up ahead, there's a slow moving truck or motorhome...and yep, that guy trying to pass you keeps you out of the passing lane, yet doesn't go fast enough so you can pass the truck....then you get to slam on your breaks ....
