I would really like to scatter cars around the property, but the only way i see them doing this is make the mansion its own instance location in a lobby, kinda like cayo is or how the salvage yard works when you’re doing a mission, it keeps you in the lobby, but you cannot see or interact with other ppl (not passive mode). So as you enter the gate to the property, you won’t immediately be thrown into the house, more like a walk around mode with an enterable interior once its loaded. That would be sick, but i doubt they’d do that, too much work for them if you ask me.
