It's a huge issue in our are area at the moment.  Kids are stealing cars and burning them up the bush pretty much every night.  They are breaking into the houses first to steal the keys.
We live on acerage on the side of town.  Last year my wife heard people walking down our gravel drive ( no, I don't know why she was awake to hear it )...........  I prefer the direct approach myself.... She rang the police...  Me ?  I ran outside and jumped in the old Rangie and chased them across the paddock at full song ....  Nothing scarier than a V8 on full choke howling out to 5000rpm with a huge bullbar on it heading for you... hurtling at top speed across the paddocks...  For some reason they haven't been back.  They sure did get through our barb wire fence fast (that must have hurt).
Oh yeah, the police never bothered to turn up ....  Some psycho asshole in a loud v8 4 wheel drive hunted for them up and down the bush tracks near our street for an hour though....  That also let all the neighbours know they were around.
I'd be way more worried about psycho assholes in 4wds trying to squish me than I would be about the police maybe arrive sometime ... hours into the future myself.
