i think power restrictions wont work. you can as fast in a 4cylinder car as you can in almost anycar.
My brothers stock 1.6L N/A laser gets to 150kph easily enuff to get someone killed.
If the driver is an idiot, it doesnt matter how many courses he does, and doesnt matter the car, he'll find a way to kill himself.
I really beleive theres isnt a solution, as some has said before "as long as theres cars, people will continue to die"
