A driving course won't increase someones ability to park...
You can't teach spacial awareness or consideration, either got it or not. And with modern cars being huge and 'enveloping' you it's often difficult to guess parameters. Had some arsehole parallel park about 2" from my rear bumper the other day - his rear wheels were just inside the end of the 5 car parking box but obviously didn't care how I was going to get out. Was quite a low saloon car so I couldn't even see the bonnet from inside the Focus! Just used the old, reverse until the bump technique lol.
