im not sure about customer screening.... unless of course the customer is pete docherty or the like (who wants a scum bucket like him associated with you?)
what i'd like is some kinda higher level or more advance driving test, just as some kind of proof that you have at least some skill and experience at handling a hi powered performance machine and that you are aware and know how to use some of the more advance driving techniques that you dont get taught when you learn to drive at 17 (or 15 is it in the states?)
you know, the driving test here really only makes sure you know how to competently drive a sedate little run around adhering to all the speedlimits and laws and what to check on your car before journeys.
it doesnt really clue you up on what to do when a 600bhp MR car starts to get its tail out all of a sudden.
Mercedes, i think, have a good take on this by not allowing the driver to completely turn the traction controll off, its abit dictatorish and opresive but really its for your own well being. ok Tiff Needel might complain because he cant do powerslides...but hes a racing driver, he knows what he's doing. mr Millions buying his first super car...doesnt (usually)
traction control is there for a reason, its there to keep things in check, and keep the relatively average driver safe from unexpected bouts of oversteer and the fast approaching scene of the accident.
if you turn it off and drive beyond your skill then your just asking for a crash.
