I said BMWs were pigs on gas. I did not say they were designed for pigs who have gas.
Also, this idea makes no sense. People who weigh 400lbs probably don't have the type of job that would allow them to buy a BMW. I'll use my work as an example. Here we do engineering. Engineers make good money, but they also move around a lot. They stand in front of the design table, they walk around the office. There is only 1 fat guy in the entire office.
Rig pigs make good money. None of them are fat.
Lawyers and doctors make bank too, but they usually aren't fat because they walk around a lot.
