okay bare with me here cos it might sound strange but........
I think modern cars have too much grip and handle too well... when they do finally let go its at a much higher speed... also they tend to be much heavier than older cars so when they start sliding its much harder to reign them in
that coupled with the fact that we refuse to teach P platers how to control an out of control car or even emergency brake
Young people should learn to drive on cars without the electronic aids, cars that have a smaller grip threshold and are generally more difficult to drive... young guys just like to take it to the edge, doesn't matter where that edge is... if its an older car that edge will be at half the speed of a modern XR6
my mates first car, a '78 datto would top out at 140km/h (and take half an hour to get there)... at that speed it felt like the world was ending, like the car would come apart...
