Ever wished the bus in game was too fast, uh maybe i'm the only one here, but it'd be more fun going up italy's hills with a fully loaded bus. Adding around 6-7tonnes of passenger weight happens regularly to city buses, so why not allow it in BeamNG examples: 35ft dennis dart, 7500ULW 12000MGW (150hp engine) E300, ULW ~9000kg MGW 18000kg (250hp engine) B7TL ULW 12000kg MGW ~1800kg (220-270hp)
Concerning bus passengers: I've said it before and I'll say it again, I would love to hear a wilhelm scream from a passenger if I get the bus airborne.
