i'm more sympathetic I suppose. More than likely they aren't just "stupid". They just haven't been taught or up to that point have not had the experience.
Watching that 3rd video, I cringe knowing that guy was sweating bullets most likely. Probably felt like the world was watching him. I know, I used to watch folks at the boat ramp for entertainment value.... and that is why and where I learned as a teenager to back a trailer well. But no matter how good you are, it's very possible to get yourself into a spot like that guy did in trying to make the turn, only to realize that you really need to just go back to plan A and back it all the way out...... It just all about how long it takes you to realize that plan A is the best choice!
The other thing I think when watching stuff like that is, oh how glad I am that we decided to buy the MH instead of a TT. I count my blessings whenever I see something like this, or when I see someone fighting to hitch up.
