Different Places, Different "norms".
I imagine cars are parked nose to tail in rows, and may be pushed back & forth to get at those deeper in the row. Done here by leaving a key, not a trusted procedure there.
If this is needed often, & for longer parking, wiring in a "parking switch" that fools the system by bypassing the gear position switches manually may be possible (Wiring diagram & electrical knowledge needed).
Those with '13's can experiment to see if there's any easier solution that works..
