Apparently, we can now be fined about $200 for being more than 3 metres away from our cars without first making them secure by winding up the windows and locking the doors.
What a load of nonsense – I believe that I’m able to determine the risk of felonious actions such as leaving a window down and take responsibility for that action.
To make these regulations even more ridiculous, there’s no mention anywhere of sports cars or convertibles (see below) – If you park your Spider down the street, you must wind up the windows and lock the doors; but you can still leave the soft-top folded on the rear scuttle.

Victorian Road Safety Road Rules 2009
213. Making a motor vehicle secure
(5) If the driver will be over 3 metres from the closest part of the vehicle and there is no-one left in the vehicle, the driver must :
(a) if the windows of the vehicle can be secured, secure the windows immediately before leaving the vehicle; and
(b) if the doors of the vehicle can be locked, lock the doors immediately after leaving the vehicle.
