Rule #11: If you start to slide or spin, just relax
I know it’s easier said than done, but if you freak the fuck out, you’ll make it worse. If a skid/slide starts, the worst thing to do is to crank your wheel and pump the gas and brake like you’re a drummer for motley crue. Just breathe deep and take it slowly. Talk to your car calmly, if you have to. If you’ve been following the rules above, you should have enough space and time to regain control. If you were driving like a dick, then maybe this will serve as a lesson in humility. Think of this calm penguin.
To regain control, moving smoothly and deliberately, looking the direction you want to go (rather then where you’re sliding to) and turn the wheel that way. Don’t brake, but perhaps tap your accelerator to give your car some traction. Once you have control, pull over at the next 7-11 and freak the hell out. You did it!
