Seriously, though, once upon a time Formula 1 cars had traction control. It was then banned to put more emphasis on driver skill. In fact, traction control, stability control and anti-lock brakes were developed on the racing circuits and some circuits still allow some or all of these systems to be used.
So, this begs a big question. If traction control had the affect of raising a lower tier F1 driver closer to the level of elite drivers, what might it be doing for you in aggressive driving?
Now, in a professional race car these systems would be tweaked to the driver's taste. Here we're talking about stock. A driver may find these systems are not to his taste in a stock vehicle. But your skills would have to on par with professional racers with repeated testing to assess the pros and cons. If you are going to turn these systems off while pushing the vehicle to it's limits where these systems would otherwise engage you better be very clear eyed as to your diving skills.
Anyway, regardless of how well you drive, it would be ill-advised to deactivate these systems other than for driving on clean, dry, well paved roads. If you're auto-crossing or drifting one day, it would be best to reactivate them the next if you're late for work and race through the rain.
