"If you lose traction with the front wheels, you can steer them in the direction of the skid."
That is a "dangerous" statement to make. Assuming you have traction control, is the only time you retain steerage in slippery condition with some traction loss in FWD. You may be able to steer a FWD in the direction of a skid....but nothing will happen. As long as the FWD wheels have no traction, you will plow straight ahead. The only exception in very deep snow with a slight "skiing" affect may induce some turning. I've raced FWD, RWD and AWD on ice.....and FWD is only effectively better if it's part of the old "free wheeling" drive of the early two stroke SAABs. Modern awd and balanced rwd is ALWAYS better.
In RWD, when the rear spinning wheels loose traction, and the car fish tails, it will still tend to follow the front non powered steering wheels wheels which retain traction.
Going down a steep very slippery road (ice covered) it is best to place car in neutral and retain steerage with FWD, using the brakes with abs to control speed.
Generally, FWD may be more forgiving for inexperienced drivers in slippery conditions at lower speeds because of the initial weight bias. The problem arises when speeds increase, and FWD is LESS forgiving than rwd. In experienced hands, balanced rwd is always superior in just about every condition to FWD.
Any "cops" out there that are in a high speed chase with any thing but a well suspended/tired/powered rwd car are at a huge, unsafe disadvantage to any one that is.
