Everyone is getting poorer gas mileage than a few decades ago, and it keeps getting worse. Engines are more efficient, but cars keep getting heavier and heavier due to all the automatic crap on them such as automatic windows, automatic trunk latches, and so forth. Safety legislation also increases weight, because it requires more steel for protection. Pollution controls increase weight. Four-wheel drive, which many people want, reduces gas mileage significantly. The bigger your vehicle, the poorer your mileage, and Americans like *big* cars and *big* trucks that match their *big* fat asses. All of which means fewer miles per gallon.
