Forgetting about the smartphone data, many cars have a Navigation system, which means the car itself knows where you are. Is it being communicated in real time, or does the car at least remember?
I actually asked someone who works in car automation this very question, and he said it's really manufacturer-dependent.
The car manufacturers are hoping no one digs into this. So let's dig.
If you sell or otherwise transfer your vehicle, it is your responsibility to delete all information (such as contacts, address look-ups, saved map addresses, or preferences) from the vehicle and contact us to transfer or cancel your account. If you do not delete this information, it may remain in the vehicle and may be accessible to future users of the vehicle. For instructions on how to delete information from your vehicle, please refer to your vehicle owner’s manual.
So apparently, if you look a place up (say, the motel where you and your extramarital partner meet), it stays with the car and/or your OnStar account.
I understand, it’s privacy and stuff, but how does _this_ make a compelling argument? Is covering up that someone cheats on their spouse, beats their kids, and launders money, now some service provider’s responsibility?
Right. If you have nothing to hide, then the police are welcome to watch and listen to everything you do. Correct?
GPS itself is entirely passive. The last position is definitely stored in the receiver to make it faster to acquire a position fix the next time it's turned on, but the question is whether that is sent outside the car. A standalone GPS unit of the type that people add as an aftermarket accessory, instead of being integrated, will almost certainly not be transmitting its location elsewhere.
On the other hand, there's money to be made by selling that data. So I wouldn't blindly assume every manufacturer just leaves it sitting on the table.
What mostly happens is that data sharing goes both ways: for instance if your embedded navigation system shows live traffic data, your car is probably sharing its location upstream, which gets aggregated and anonymized according the legal framework and the terms between both parties.
You can do stuff with a car that you wouldn't be able to do with a smartphone, for instance using sensors to scan curbside parking, whereas Google needs to extrapolate street parking availability based on driving patterns. But I'm not aware of anyone doing that yet... I've only seen proofs of concept.
Do you know that for a fact?
The dealer charges about $200 to do it. It's probably possible for someone to do it on their own, but I don't drive enough to bother looking it up.
No. its' a second hand buy. maybe if purchased directly
> Could the police subpoena it?
it's also an import. probably any info is saved in a server somewhere in germany. Possibly yes, but which police ? in which country ?
If you were sitting on PII location data and no one knew you had it, you'd probably want to keep it that way. Going public would certainly get the authorities after you.
