It's standard memory vs performance. For iterators you'd need MAX_PLAYERS * MAX_VEHICLES memory cells (as multiple people can see shared vehicles), so for example if you need 2000 vehicles for 50 players, you already take up 10000 cells. Not to mention adding and removing them from your collections. I doubt everybody will press that button all the time, so I'd say computing it on the fly would be more performant. Also IsVehicleStreamedIn is a native function, so it shouldn't be much overhead. BUT, if you are still worried about performance, you might split your map into areas, and keep track of which vehicle is in which area. Then, just check current player area + neighbouring areas + IsVehicleStreamedIn for maximum performance. I'm not certain, but maybe your particular vehicle streamer contains some function like GetVehiclesStreamedForPlayer?
