Actually, Funbun .... most people do not have their vehicle between the boat & house, so they're not going to have to back the boat out of the driveway. But, I get your point about beginners learning to physically turn and look back at the trailer to see which way it's going when the steering wheel is turned L/R. The idea of learning to use your tips in a empty parking lot wasn't made to diss your method, but likely to give the inexperienced person a more comfortable area to make mistakes in .... just like when teaching a person to drive (and not destroy your belongings or those of the neighbors).

I think the others were simply adding their take to the next steps of learning, which this tip video didn't portray ... but which your following videos will. They just kinda jumped ahead of the process. No reason to diss them for that.

Remember .... the #1 unwritten rule of this site is to "agree to disagree, and do it with civility".
