I have it for Gamecube, so I can't go online, and I think it's fine. Then again, I've never played a console game online.
As for the cars/blimps/leaf blowers/limos(I think that's every vehicle you can drive) and walking/climbing/jumping/shimmieing, it works. You have to help out your friends by getting onto roofs, and you climb onto roofs to film awesome footage. Also the vehicles are just helping out local people. It's fine.
