AAMI is doing a great job with giving people incentives as discount on insurance if they take a defensive driving course...a friend of mine (under 25) did it a few months back and gets like 15% off...

they teach these techniques on that course plus a lot more simple things that wouldn't really come to mind when ur behind the wheel...
e.g. he was tellin me about debris in the car causes just as much, or aybe more damage during a car crash than the crash itself...a baby was killed, even though it was strapped to an approved capsule, by a mobile phone sitting on the dash and went flying hitting the toddler on the head...
