even a school bus FULL of kids is running around essentially unloaded. what do they have a few thousand pounds of kids in there? any v6 pick up can haul around a few thousand. you dont need a monster dually school bus with 22.5 inch wheels for that.

the main reason those gigantic school busses are used my friends, is child safety. you could ram one of them busses with a typical car at a high speed and not even bend the frame. larger vehicles would do more damage, but school busses are built big, tough and heavy on the iron and steel. it's a safety issue. same reason why they run school busses on diesel. it's not explosive if a tank was to rupture and leak. if the bus was gasoline fueled and a tank ruptured the gas can burn and boy does it burn! diesel burns incredibly slow in our atmosphere.

anyone ever try to light a cup of diesel on fire with a cigarette lighter? it won't even light. try that with a cup of gasoline and you have a pretty decent flame.

try pouring diesel on the sidewalk, or dirt and lighting it. it usually wont even light. try that with gasoline and it "whoof's" and burns you feet.

*^*don't actually try any of those things i said *^*
