Couldn't find any other topics on this, so here goes. I know that loot and zombies don't spawn/delayed spawn when the player is traveling in a vehicle and no other players are nearby. What I'm wondering though, is whether other vehicles spawn when you are already in one? If I grab a bicycle or small car and go scouting through all the common vehicle spawns, do I need to get out of the car and wait around for a few minutes?
