What am i suppose to be doing?

I know this game in in-dev,
But for like 3 months while playing this i game i get on sandbox and make a couple body’s, a couple engines then then get off. That’s all i know how to do. Is there more to this game at this moment that i don’t know about, I’m sure when the campaign comes out this game will be killers. But for now what’s everyone doing? Can i get some suggestions on some fun things to do? Or is everyone just kind of messing around just like i am.

One way to make this game fun, is to either get involved here in the forums with the competitions and the like, or bring out your inner Roleplayer/storyteller and create stories behind the cars in the car design sub.
