That's an interesting point Sicknote, and has some merit. However ...
I'd wager that many who are caught in the spin off final turn though, are those used to bigger circuits and then one day (probably under pressure) find themselves having to turn tighter than they're used too and over rudder! A well banked but balanced turn, if flown properly, is far, far safer than being frightened to bank and subconciously trying "will" yourself around the turn and applying that bit too much rudder. Take a slipping turn as an example, you can have bootfuls of out of turn rudder applied, a crazy bank angle and huge amounts of sink ... but you will not stall and spin. If inexperienced pilots were taught to be less frightened of banking, but not allowed to fly out of balance when doing so, there would probably be a reduction in such accidents.
