It really depends on who attends. A member that hosts a lot of car meets will have a list of good and bad players that he'll refer to. If spots need to be filled, he'll contact the good players. Bad players will be told they can't join or kicked. The thing I hate is when people put up with bad players and THEN don't invite them back. Just kick them. For me, a bad player is someone that constantly rams others and starts fights for no reason. Oh, blowing up cars is a big one too (once intentionally, twice unintentionally - are kicked from the lobby). Also, car meets in a public session is like trying to light your cigarette in a barrel full of dynamite. Yes, you can get most of the lobby to be chill and join you but all it takes is one idiot in a jet/tank/helicopter to f*ck things up.
I don't really attend car meets anymore. Too much waiting in parking lots. Wish there were actual cruises instead of "car meets" where people just park their car and call another to show them off. Congrats on having a garage that isn't filled with bicycles.
