Actually, any GPS or location enabled device with a network connection of any kind IS a tracker. The wireless carrier records that information passively, ALL THE TIME.
In fact, any device that merely sends out a unique ID (i.e. Bluetooth or WiFi) can be tracked, too, only somewhat less conveniently. It's how stores 'follow' people with cell phones in their pockets. They don't have an agreement with the wireless company. The phone is emitting a digital signal with a unique ID over and over again, wherever you go. They simply listen to it.
Smart phones practically all have 'location' enabled, whether you disable it for your apps, or not, and follow every step you take with it in your pocket or purse. They all got caught, and the wireless network providers simply added this to your terms of service. You agreed to have your movements tracked and logged, in order to activate that phone.
Cars with 'OnStar' like functionality are the same thing. Getting OnStar NOT TO track you, even if you're not paying to have it activated, is a hassle. How much storage to log a car's VIN and position every minute for a year?
ICBM Address: 36.8274040 N, 108.0204086 W
Time: 201204241841
VIN: FJKL19862004380
Call it a generous 64 bytes, if completely in ASCII (though in binary, it would be about 32 bytes).
36.8274040 N, 108.0204086 W, 201204241841, FJKL19862004380
525960 minuts in a year, times 64 = 3,3661,440 bytes
So a million cars can be tracked in less than 4TB of data (given an absurdly generous 64 byte record size, and minute resolution). That's $180 worth of storage for you or me. For a big old corporate storage center, that kind of capacity is chump change.
A lot less space, if the resolution is down to one sample every several minutes, and is packed more tightly in a binary format, and doesn't record duplicate positions (i.e., if the phone or car hasn't moved more than ten feet, don't send a 'duplicate' record).
Just replace VIN with 'cell phone ID', if you like.
And that data is valuable. Police forces want it to see where your car has been, or YOU have been. They didn't have to attach anything to you or your vehicle. You voluntarily carried it. They didn't need a warrant. You consented to the corporation recording your movements 24/7, AND 'sharing' that information.
Other corporations would love to know where you drive, where you walk, when. You agreed to let the wireless carrier or 'onstar' or whatever 'share' it with partners. Practically every car dealer in your city knows your car's VIN. They recorded it when you bought it. It's 'shared among partners' as part of your loan or lease documents, including your SSAN. They all start pestering you in the last year of your lease or loan contract. Your cellular carrier also has your SSAN and credit info. All of this can be cross-referenced.
So they can watch every step you take, and every plastic transaction you make. Your credit card banks and bank 'share' information with 'partners', too, after all.
