Data sent by vehicles and companion apps included locations, VINs, and other identifiers. Amazon, Google, Meta, and Microsoft were among the top receivers of driver data.

We just bought a new car this year (Kia) and I completely confused the sales lady when I told her we were not going to use the "connect app" or activate connect on the car itself. She was like "lets get you setup in connect" and I was "no thanks"

We have a nice 🚫 symbol with a radio tree behind it, so I 100% know the car is still connected to the cell network but it is not registered/connected to us, and no app installed.

Sure, we lose some functionality (remote start, and access to in-car wifi) but all of that is paid subscriptions. Sure they first x months are 'free' but after you gotta pony up $ to continue.

Note: I'm under no illusion tracking is just not happening for us now... I just want to make it harder where I can.

My wife just got a newer car last week so I'm asking you because you know more than I.

We never connected a phone to it but the GPS worked right off the bat. Do cars have standalone GPS now? As long as we don't connect a phone, it can't reach the internet, right?

[–] asbestos@lemmy.world 21 points 5 days ago* (last edited 4 days ago) (1 children)

Cars have had standalone GNSS (GPS) for quite a while. GNSS itself doesn’t require internet. Its output is coordinates and elevation - it’s the “gotta have internet to load the map in which I’ll show you the coordinates” that makes people associate GNSS with internet. Offline maps solve this.

[–] Buckshot@programming.dev 7 points 5 days ago (1 children)

Unless it has local maps like mine that are now a decade out of date. It's completely useless now but i refuse to pay several 100 for the update.

[–] boonhet@sopuli.xyz 4 points 5 days ago

If it's a decade out of date, it may be old enough that the maps live on a DVD or SD card, in which case you might be able to get updated maps for free. Yarr!

My car isn’t because it’s old and stupid.

[–] mrmisses@lemmy.world 19 points 5 days ago (1 children)

I hate my 2013 Mazda but also love it. Stupid and full of bad memories

I just sold my 2013 for a 2011. I'm reverting!

Researchers connected each vehicle to a custom WiFi access point and logged all outgoing traffic.

The article talks about both apps and the vehicles themselves. I would really like to see more info on what the cars do when you take the apps out of the equation. Are there any that don't phone home unless you explicitly give them internet access?

A study about the results will be published this week.

I look forward to reading this.

Edit: actually there's quite a bit more detailed info at https://automatictransmission.khoury.northeastern.edu/

[–] Corngood@lemmy.ml 3 points 5 days ago (1 children)

I'm still not sure if those require giving the car a WiFi/cellular connection or if it'll just use it's own... I've heard that cars use their own SIMs to phone home, but I don't actually know how prevalent that is

[–] avidamoeba@lemmy.ca 7 points 5 days ago

I know for a fact Ford ships a modem with a SIM and they use it sparingly because it's expensive. Don't know abt the rest.

Would REALLY love to de-surveillance my vehicle if anybody has any tips (please quietly make the "buy an old car instead" jokes to yourself)

[–] db2@lemmy.world 10 points 5 days ago (1 children)

Find and disconnect the telemetry antenna. If the telemetry is in a discrete unit delete that too.

Don't do anything irreversible in case the manufacturer has booby trapped the car to go in to limp mode without the portable flock setup.

[–] diaphragmwp@discuss.tchncs.de 2 points 5 days ago* (last edited 5 days ago) (2 children)

Okay, but how do they fill the giant hole in the middle of the dash now?

(/srs can just cut off all antennas but this will make the computer waste battery trying to connect so the car may not start after a while if it's combustion engine)

In many cars, the modem that phones home with your data may be a separate unit. Depending on your make and model, you can sometimes buy cable adapters that will connect power to everything except that subsystem. The term to search for is a "DCM bypass plug".

(please quietly make the “buy an old car instead” jokes to yourself)

That's not a joke, it's sincere advice. My newest car is a 2008 (I think) model. I'd love to have an EV, but I don't because I haven't figured out how to have one that isn't infected by "telemetry" and other enshittification. I have hopes for the Slate Truck, but it doesn't actually exist yet, so I wait.

(Also, yes, as a mod of the place I'd be remiss if I didn't second the other reply and suggest adopting a non-car-dependent lifestyle to begin with.)

[–] Boost@lemmy.world 3 points 4 days ago

Many cars have the modem / LTE as a module that can be disabled. On my car, a 2018 Chevy, the LTE antenna plugs into a networking module in the footwell. I bought an antenna cable and dummy load resistor on Amazon for ~$10 and simply unplugged the LTE antenna in the car and plugged in the dummy antenna. That disables all cell network connectivity but doesn't effect things like Bluetooth. It's also easily reversible if someone wanted to do that for some reason.

You can probably Google something like "year make model disable LTE" or "disable telemetry" to get an idea of how hard it would be on your car. Some make it very cheap / easy and some make it very difficult.

And if I were to use a screwdriver to pop a component off of the motherboard, which website would tell me the component to target for my make/model?

[–] halfsak@lemmy.world 6 points 4 days ago

Disconnect the antennas. Its easier and reversible

I'm driving my crv until the wheels fall off and then I'm gluing them back on

The one time I'm happy that Toyota was so far behind the competition - I've a 2020 Prius and its infotainment looks a decade out of date but that means it's very offline.

[–] hneerqe@lemmy.world 11 points 5 days ago

Would rather drive a rust bucket. I do drive a rust bucket. I'm not affraid of scratching it. I don't feel I have to always keep it pristine clean. I'm not affraid of working on it myself. I'm not being ~~charged~~ robbed subscriptions for equipment already installed. I'm not wondering wether I'm being tracked by sick fucking creeps.

[–] Joelk111@lemmy.world 4 points 4 days ago

I hate this style of titles. I'm a gearhead and own 5 vehicles and a motorcycle. None of them are a smartphone on wheels, the newest one is newly 20 years old.

[–] Pat_Riot@lemmy.today 7 points 5 days ago

2006 car with manual transmission. There's exactly enough computer in it to run the ignition and oil change timer.

[–] Mulligrubs@lemmy.world 8 points 5 days ago* (last edited 5 days ago) (3 children)

I have a 2008 car, it doesn't even chime when I don't put my seatbelt on.

After driving a 2024 Subaru, I realize that I am a very fortunate person, and I live a life of silence and peaceful reflection.

2010 models at the latest, I am only going to own old vehicles until this beeping madness ends.

How long until new models show advertisements on the dash related to your conversations? Three years, tops.

I hope the study specifically publishes the data on the Model 3. I bought one before I became much more privacy conscious, but I've done my best to mitigate the leakage from that. In doing so, I read through all of Tesla's terms and conditions upon opt out and sending any of my information or information that can be used to identify or profile me, should never be sold to advertisers. I write software licenses for a living so I'm pretty confident in my reading on this. It would be interesting to see what can currently be mitigated by changing some settings and what cannot.

I just need to get from point a to point b. I don't need some goddamn home entertainment system connected to everything else.

No it's not. You don't know what my car is and is not.

The ECU in my 1991 Chevy k2500 is little more than a desk calculator that can turn throttle position into injector duty cycle and ignition timing. Good luck advertising companies.

Just get yourself a '97 4Runner, there are no trackers in a '97 4Runner.

[–] Blaster_M@lemmy.world 4 points 5 days ago* (last edited 5 days ago) (2 children)

Interesting to see Subaru at the very bottom - barely anything, but Toyota is the opposite, sucking up big data like they're General Motors

Edit: can confirm my car isn't doing anything - when I upgraded my head unit, I discovered unconnected wires where a telemetry module would be

While I have a 2024 Honda Civic, it doesn't have a cell connection (though it does have a form of GPS). I'm fine with that, but I'm surprised that it didn't even have that option.

[–] mx_smith@lemmy.world 7 points 5 days ago (1 children)

You can disconnect that cell connection. I have a 2018 Accord and there is a module in the trunk that has a plug you just pull it out.
