At minute 1:28, I'd be pissed off if that idiot threw a bunch of rocks like that onto my new car. That wasn't just sand. Minute 1:52 he's still swerving and kicking up debris. Sure is showing professional courtesy on the road for making almost 70 cpm!
At minute 2 he's crossing into the lane next to him.
At minute 2:12 cars cannot pass him in the right lane because he's half way into it.
At minute 2:25 he's still has his whole set of duals in the right lane.
At minute 2:33 he still can't keep his truck out of that right lane if he's going to hold up the center.
At 2:45 he still has his rig deep into the right lane.
At 2:57 he goes in deep into the right lane as a car is trying to pass him while he's holding up the center.
I get most of the new breed thinks this is ok, but this is clearly not professional driving. Watch the whole video, not just the first 30 seconds.
