So they can watch TV while filling their behemoth SUV?

Given the advertisement:content ratio of most US TV and the gas mileage of the average SUV, this actually starts to sound like a good idea.

Think about it: You watch a segment while filling up. Then you drive away as the adverts start. By the time the tank's empty, you should have just about got to the next gas station, and the adverts will just be finishing, and the next segment starting.
