I have watched this more than once and felt it necessary to post it up.
Every time I go around a blind curve I will think of this. Once, on old Route 66 riding to Oatman, AZ a motorhome did the same thing. There are several signs stating "No vehicles over 40 feet".
Sure enough it was one of those long babies and pulling a car! Thankfully we were both going slow due the curves.
It was close.
