Gas prices & driving habits

With gas up near $3.75 a gallon and hearing everyone complain about it you would think that people would slow down a little to help get a little better gas mileage. I drive the interstate everyday to work and get passed all the time by people driving 80+ mph, what really amazes me are the people who drive like this in trucks with big V8 engines!!!! Americans are an interesting people, they love to complain but they sure don't want to do their part. Kinda like people who complain about how much money they make but don't have a problem with being in debt? Ok, I'll leave it at that :)
