I was on the highway a few weeks back cruising along at the limit, 75, and just as I was approaching a BIG hill this truck swings over to the left to pass another truck. By the time we got to the top of the hill we were all going 64, and then the truck finally edged pass the truck on the right.
I always try to make sure I stop and pee whenever I need to, I think it helps keep me in control, but stuff like that is pretty bad.
I don't have one, but I have read dash cams, like those the police use, are pretty common in some places.
Maybe they should be required, kind of like a black box in a plane.
