Best way to reverse is like the HGV driver’s do, use your mirrors!, not the stupid way they teach you on your test, turning around and looking over your shoulder!, that idiotic way needs removing from the driving test now!
I once pulled up on a caravan site at 10 pm and went the wrong way!, I successfully reversed using my mirrors, with the caravan on the back, the full length of the site, in the dark!
With a bit of practice it became second nature!, I never look over my shoulder anymore while reversing.
