I did a speed awareness course a few years ago, I found it extremely beneficial to be honest. The person running the course managed to communicate very well and I came away with a deeper insight into why limits are in place, and how the excuses for people speeding - stuff like "it's just a way of raising revenue", "I was driving perfectly safely for the conditions" and so on - are usually just masks for a kind of high-handed arrogance, a belief that "the limits are for other people, not for me", something I realised I was guilty of myself.
Now I stick rigorously to all non-NSL limits, and reserve my playing for NSL sections times when either there's no other traffic or cameras about.
It's amazing how much fun you can have on a 60mph B road without ever breaking the limit.
