Bobby Dee's idea of cars holding more than two people is great, but what if those people could shoot? I think you should be able to shoot if our the passenger of a car, so your gang can clear out the outsides of forts, or you can rack up a streak. This idea also leads to an event idea, there should be a drive-by event, where you have a team of two or so, and you have to drive around in a small area and kill all the other teams.
Good Idea?
