Yeah, the forum I got this from, they were talking like it's great technology, "should of had this a long time ago..."
One said something like, it would be great, then I wouldn't have to strain my neck trying to turn my head to back up a trailer...
I broke my neck, and can't turn my head even if I wanted to that far. Isn't that's what mirrors are for!
I was taught very young to back up a trailer with a truck, and a wagon with a tractor, so backing up anything is pretty easy to me.
