No, but the arguement is that IF someone were to fill each seatbelt, the average weight of the occupants would have to be under 150lbs to meet the govornment calculated/mandated payload capacity. in the caddy XLR, A 400hp 2-seater with stiff sporty suspension, the total payload capacity is ~350 lbs. if I drive, that leaves 175 lbs for a companion AND luggage. Granted that car's a weekend car at most but even a sedan with 800lb capacity and 5 seatbelts can be overfilled in no time flat on the family vacation a couple times a year.

I'm about 185 right now,but hope to lose some( mostly so my clothes will fit again).
On the other hand if a few passenger's at 300lbs each can really add up; which I believe added to Firestone's problem a few years ago; as family and other group's crowd into SUV's in search of yet more food.
I am 180 6' up a bit from my usual 165lbs but everyone was saying I was too thin and most of it is muscle. The xB once carried me and 3 other full size adults and a few hundred pounds of sailing gear including three sails for a 42' sailboat. It rode nice even over the railroad tracks but took a lot more engine revs to get going and get up hills. The 10 mile trip still got me over 40mpg. My Geo would usually bottom out the suspension on road bumps with just me in it but near as I can tell the xB has not bottomed out yet.
Lol Jangeo, one time I was working with a couple guys tearing down a barn and we all jammed in my metro to pick up some snacks at a nearby gasstation. I estimated there was about 875lbs of just people in the car. Tops of the tires must have been about 1/4" away from the wheelwells cuz every little bump bottomed it out :P
