Be careful when doing this. A few years ago a guy in a semi hauling coal did this and the idiot did not back up. So the semi driver went over the idiots hood with a set of duals. Too bad the idiot was the local "I'll sue at the drop of the hat guy". Not sure how that lawsuit turned out but a local judge finally told the idiot he could file no more lawsuits unless he the judge approved. The idiot then moved away so he could sue again.I have a "friend" who does this, or just about anything else, to SAFELY scare the out of a driver that's in the wrong. By the way, said "friend" does this in a 128,000 pound fuel tanker.
For folks that pull up way past the white stop bar at a stop light in the left turn lane, I, I mean my "friend" will purposely take the right hand turn as wide as possible and make them back up. Then they usually flip the driver off.
