I honestly don't bother with reverse bay parking - I find it a lot easier to reverse out. Basically the longer you drive by yourself the more you will realise what works for you - as long as it's legal and safe it really doesn't matter too much, 'manoeuvres' are basically things which give you the tools to control your car better, they don't have to be the be all/end all.
And as other people have said, screw other drivers - just stay safe and legal and you're fine. I drove from home to Uni at night for the first time recently, roughly a 2-hour drive along busy motorways, and I was shocked by some the stuff people try at 70 mph xD
