Sim Aspect and other ideas

I was going on about having a really in depth social system with a friend and they agree that having a sort of simulator aspect to the game and or maybe items and abilities to boost stats on. 

So like possibly having to eat and or having health systems implemented in certain game modes and or challenges that would make the game and other activities more meaningful. Other than showing off our skins and our hard earned clothing, maybe go deeper into how people will want to interact with the game. I see so much potential to lose myself here and spend loads of money on in game items that are earned through skill and not to bought. 

Im assuming you guys are going to have social hubs already planned, seeing we have to return to the shops to upgrade them, but I would love to see events and some trading happening. Trading skins and colors and wheels and trucks would be insane! making the players feel as if their own accomplishments are worth more beyond the game. Their skill being the glow! 

People have already suggested gangs and crews and such which I am a fan of, but not only add that, add turf challenges and real skill challenges that players will have to compete for to make a name for themselves. Ive seen the fresh added digital billboard with founders on it, but having a crew name tagged on one part of the map would be sick.
