Some of the fastest people I've seen out here in bumblefuck New Jersey are in fact morbidly obese or damn near it.   I saw a fat ass struggle getting into his lifted (I think that's the term for higher truck cabs) pick up. Took him nearly 2-3 times longer than a normal person to get in. Also, I'm sure either the suspension is fucked or he was just too fucking heavy and the suspension took the abuse.
