I like to play turf zero and i thought it would be cool if there was buildings for specific vehicle spawns. Like police stations that spawn stronger types of police in its aoe (two in one car or shotgun) but increases general building desirability. Military bases that spawns jeeps and allows tanks to spawn. Helipad spawns choppers randomly and ads commercial/office desirability. Car shops that spawns tricked out and fast cars. Bus stations for buses and taxies and other buildings.
