Actually it does seem to. Police won't even 'investigate' if your car wasn't locked. Growing up I was always told it's better to leave it unlocked so you don't have to replace a door or window over some spare change. Turns out the breaking into a locked vehicle is the only part of the crime that law enforcement cares about. Now I always lock my vehicles because taking things from an unlocked car is apparently not a crime. Anyway, not defending the analogy, just expanding on it.
