I think that most people would be shocked at how well some of these career truck drivers can back trucks. I've seen some crazy backing that I didn't think was possible.
Yep. The other reality is they aren't going to put a newbie or unskilled truck driver on that haul. The last thing any trucking company wants is ABC saying "XXX was unable to play today because their equipment truck crashed on the highway. Here's some live shots of the accident" and they cut to a video of the trucking companies logo plastered over the side of the truck with the equipment trailer split in half on the side of the highway.
As far as protective bollards and such, renderings never show that stuff. That or they use architectural measures to disguise it. Like Target does with those big round concrete orbs that are in front of some of their buildings.
