I agree but….. You do not see the turn until you are well within the concrete barriers. Your brain says there is no way they would design a MAJOR onramp so that trucks, RVs, and trailers will hit the barrier. You have a line of cars behind you. To un hook and back both vehicles out with a dozen cars honking is just hard to imagine. In hind site you are 100% correct. I ended up backing out anyway. Just hard to believe they would do this. In examining the barrier 100s of vehicle had hit it. Some markings were at the top of the barrier.
