Not to mention dog/deer/kid pops out in front of 59, who veers left and never sees the 'creeper' in their blind spot and you have a real mess.

(When I'm on the road and someone pulls that stuff, I tap the brakes so they go by and the lane is clear behind them/beside me. I use those add on convex mirrors, too, which will show someone in by the rear quarter panel.)
