Where can I find the driving laws?

If your windshield is fogging up you need to let fresh air in the car. Open the air vent to fresh and not recycled or recirculate. Most newer cars use a mixture of heat and air conditioning when you use the defrost setting. The fresh air mix helps take out moisture from the air which causes the fogging up on the inside.

What's the funniest bumper sticker you've ever seen?

Hot air. Two things happen when you turn on your defroster. If your car has Air Conditioning the A/C compressor automatically turns on and the fan blows air through the ductwork at the bottom edge of your windshield.
Having the AC compressor come on lowers the humidity of the air being blown, having the air hot lowers it further so the moisture on your windshield can evaporate more easily and clear your view. By chance, if your windshield keeps fogging over worse and worse, and you smell antifreeze, you have a small leak in your hearter core and need it replaced. It doesn't sound like you have this problem though.
