i think the trackers are a great idea, because any technology can be fooled or bypassed so its basically an opportunity to save loads of money.
lets assume the tracker is the same as the very best vehicle security trackers (probably wont be as good due to cost but better safe than sorry)
the tracker system works even if the car is switched off, even if its in a house or garage or multistorey car park, even when the battery is disconnected, even if its in a shipping container with lead plating on all sides (as thieves discovered more than once). you cant switch it off or they'll notice straight away. so how do russian car theives manage to send police on wild goose chases just for the fun of it when stealing supercars across europe?
all you need to do is create a cloned tracker on a standalone system. you disable the incar system after you activate the stand alone system, making sure they both have synchroned codes in exactly the same place during switch over (luckily the tracker system cant distinguish between 2 identicle code series in exactly the same place due to using only the code as the identifyer, if they added something else it can also be cloned, even a rolling code can be cloned if access to the tracker's chip is available, just like a remote key cloner).
then you leave the standalone clone tracker in the garage while you drive around where ever you want as fast as you want with no risk or cost. obviously the average joe wont be able to bypass the system, and the goody goodys wont want to, but anyone who really wants to will be able to, thats the law of technology. the other law is that it will be cheap enough for the vast majority of people who want it to afford it, thanks to market forces the people who sell it wont want to price themselves out of the market, and as more people offer the service the price will drop further. the hardware costs cant be very high, a security tracker system doesnt cost much, its the labour to fit it that costs more, and the subscription costs are a pain. with a tracker bypass you only need to by the clone tacker once and pay for the clone coding service once.
i bet they'll even advertise the service in your local paper one day, in exactly the same way they advertise 'milage adjustment services' now, they're just mobile car clockers if the truth be known. the tracker cloning adverts will probably read 'tracking system upgrades and repairs' or something like that, and for a few hundred quid you can decide how much tax and insurance you pay. as long as the recorded use is realistic you wont get caught.
