I&#x27;ve heard advice that if you don&#x27;t have any valuables in the vehicle, leave the windows rolled down and the lock unlocked so anyone who thinks they can steal something won&#x27;t do much damage getting in, and the fact that it&#x27;s open in the first place discourages them from believing there&#x27;d be anything valuable inside.<p>I&#x27;ve seen stores leave tills empty and opened after they close, presumably for the same reason.
