If they're not about saving money, why do people get concerned about their effective miles-per-gallon? If people were concerned about the environment, we'd be rallying the EPA to talk about the amount of greenhouse gases being laid out by the car's production and use. We'd also see people riding bicycles or walking to their offices that are a mile away instead of letting their car warm up for 15 minutes and driving. There's noting wrong with wanting a car because it looks cool, because it has some hot new piece of tech, or because the amount of dollars you spend on your car somehow makes you feel better about yourself. And to those people, fuel economy makes little difference.
