So I've been around the forums and been hearing lots of compliments and complaints about the game but the most frequent ones would be premium and the high payouts.
So I thought of something, this will vary among factions but an income feature where you could drive to a place to pick up "protection money" from stores.
There would be a rate at which the money comes in and a cap on how much the store can hold. Players can also buy upgrade such as more money per/h, shortened intervals or just being able to hold more cash. I would propose to only be able to use one upgrade at a time, maybe with premium, you can have an extra upgrade slot or enhanced upgrade.
