Re: WIND

Just drive backwards.
The aerodynamics of the car will suck you forward.

This uses no gas at all.
In fact you will notice that your gas level actually goes UP.

Yes again, but here you are comparing force to energy. The force is proportional to the square of the velocity, and the ENERGY required to generate that force is proportional to the cube of the velocity.

Actually, I don't seem to take a huge hit when the roads are iced; the reduction in speed (like this morning, from 60 down to 40-45) seems to offset any increase in rolling resistance. Come to think of it, is it possible there's a *reduction* in rolling resistance on iced (not snowy or slushy) roads?

Then again, I guess not everyone slows down - like the tourists, or the 5 cars I saw off the road today (all 4-wheel drive, btw - will they **never** learn?)
