This is easy. Being 17 i can tell you what did work. Basically tell him that driving is a right and not a privalidge for him. Tell him that he will have zero transportation if he damages his car because daddy wont buy him another. Tell him that this car will make it through college or he will have no car. Fatalities just fade in one's memory, if you make it his own responsibility like somewhat mentioned he might take pride in his actions. Don't allow him to learn the hard way, it's been done that way too many times. If you give him control he'll take responsibility, not the reverse though. I am impressed of the actions you have taken so far. do what i said and all will be fine. Try to instill in him that one action can make or break his life- the process is self actualizing.
