Is it not true that the rising number of SUV's and trucks creates a higher demand for gasoline, which forces prices up for every driver?

Is it not true that when someone buys a whole bunch of candy canes, that it creates a higher demand for candy canes which drives prices up for everyone? Yet I don't see anyone complaining about candy-cane-eating fat people? And fat people are also hard to see around when you're behind them on the sidewalk. They can also have a tendency to give out more than average air pollution after eating mexican. Yet why isn't anyone fighting for CO2 emission standards for fat people? I'm sure if a fat guy and a little guy have a collision then the little guy is gonna be a lot more hurt than the big guy. But nobody cares.
