Fog Lights

So with Gas Prices heading towards 2$ a litre every radio station, tv station and website is spending hours, or pages, telling people how to save gas. Everything from removing weight from your car 1-5%, using a lighter foot on the gas pedal 10-35%, or keeping your tires inflated 1-10%. All of these strategies tend to increase milage just slightly which is always good. The issue I have is that I see soooooo many people driving around with their fog lights on, and I can't understand why, having those lights on will reduce your gas mileage just the same are removing some small amount of weight from the car and they can be turned off with the flick of a switch and not require you to remove your safety kit from the car. The other thing is that it's just annoying to have some one in their big truck come up behind you and bathe the whole of your car in the light of all the lamps in front of the truck. It may also be Illegal in some areas. I would love to see car manufacturers take the lead on this they can make cars in which all maner of things have to be turned on each time you start the car, cruise control, defoggers etc. but for some reason they have left the fog lights (something you almost never really need) as a fixed switch that is on forever if you never turn it off. well here's hoping that someone will make that kind of change in a car/truck and stop the blinding/resorce wasting.
