I have no idea what the solution to that would be. I think that more needs to be done to make it seem 'real' for the teens - by that I mean the accident survivors who travel around the schools and tell them how hard life has been since they became a paraplegic/amputee etc. You're right, they are so desensitized to what they see on TV, that it doesn't seem real to them so that's why I think taking a personal, real life approach would work. I know there have been times where they have shown kids what a real wrecked vehicle looks like and even SES demo's of cutting people (dummys) out of cars. What worked for me years before I had my license was in yr10 and we went to Sydney for an excursion and part of it was going to the Surry Hills police station and we were shown actual crime scene photos of the Grafton Bus crash, Granville Train crash and other assorted vehicular crime scenes and seeing those real people with limbs missing, skulls broken really rammed it home for me.

It's something I'm thinking more about lately as my 16yo brother recently got his L's so we've been ramming home the need to drive responsibly etc to him.
