I can recall reading that in the UK there was a GPS/engine immobilizer that could be fitted to any vehicle for about $A700.00 (10 years ago). I recall thinking that if you were 'filling up' and 'Joyriders' came along, you could make a 'phone call to one central point and give them an 'authenticating' code and they would immobilize the engine, which caused a 'splutter' and a thirty second 'delay' so that the driver could pull over, and then the engine would 'die'. Also, the location would be available via the inbuilt GPS tracker for the Police to round them up, if they had hidden the vehicle in a shed or container.
I cannot believe that it is not mandatory for all new vehicles to be fitted with them.
I don't know if they are available in Australia or if there is a central 24/7 'command', with the appropriate Satellite, to contact if you did purchase one.
Perhaps someone else knows.
