I can reverse well, due to narrow lanes around here. Can reverse trailer when I don't think too hard about it. I find its a sensory thing, I know when it won't work before I've gone too far. Hubby taught me to drive and reverse. We have a small narrow trailer that is a real bitch to reverse in an old landy but easy on a quad bike. A big trailer can often be easier than a small one. Totally agree its less likely to work if people staring. Spent ages this summer teaching my 13yr old to reverse the small trailer but he did get the hang of it, daughter didn't though.
