When an unused vehicle despawns
The time after which a vehicle is removed if nobody uses it.
scum.MaximumTimeOfVehicleInactivity=240:00:00
What does this setting do?
The format is hours:minutes:seconds, and the default of 240:00:00 equals ten days. If a vehicle is not moved within that window, the server clears it away.
This is not merely housekeeping; it feeds straight back into vehicle availability. Because parked vehicles count towards the maximum for their type, every forgotten car blocks a slot. Without this timer nothing new would spawn after a few weeks, since all slots would sit parked inside bases.
Conversely, too short a window punishes players on holiday. Ten days is a sensible starting point; go below it only if vehicle slots are genuinely tight.
Which value suits my server?
360:00:00 (15 days). A holiday costs nobody a vehicle.
240:00:00 (default).
168:00:00 (7 days). Not playing means losing your slot.
What to watch out for
The clock runs from the vehicle's last movement, not from the owner's last login. Play daily but never touch a second vehicle and you still lose it.
Shortening this window applies retroactively to everything already parked. Without warning, vehicles vanish en masse after the next restart — the surest way to upset your regulars.
