       I bought a car. I’m trying to get Toyota to stop sending telemetry. I call support. They tell me I can just sign in with the app and make changes.I point out that installing and using the app binds me to terms and conditions, one of which is binding arbitration. So I will not be installing the app.No, no. The customer service agent confidently contradicts me. You don’t sign a contract by installing the app. It’s just like making a Facebook or google account. 🤦🏻

       @paco And you believe buying a car doesn't bind you to any terms and conditions relating to telemetry?

       Lots of commentary on this and many people say “just take it out.” Yes. That’s sorta possible. This video shows what it looks like when you get access to the DCM. You have to disembowel the dashboard. https://m.youtube.com/shorts/Y_heoO_SGOw?ra=m

       @paco Time to figure out where the modems/antennas are and disable them (unplug, remove, cut…).

       @isocat @paco If it's not already the case, and disabling external communication becomes a trend, I see a future were manufacturers force you to service the car (error messages, or straight out refusing to turn on if, say, connection has failed for a number of days). Enshittification at its best.

       I’m looking into it. I know a couple things for sure. Data collection is opt-out, the modem is buried deep inside the dashboard (so a huge PITA to get) and the phone microphone runs through the DCM (data communications module). For $70 I can get a bypass harness that you put in place of the DCM. It’s just wires with the right connectors and it keeps a few things connected (like the microphone) that would be disconnected by simply removing the DCM.What I am uncertain about is how to get to the DCM. For a lot of cars (RAV4, Camry) there are published instructions. I’m not afraid, but I won’t do it without instructions. Also, the symbol on the screen that indicates DCM is not working is already indicating that. When I spoke to the folks in customer service, they did some stuff on their end. So I’m not sure if it’s transmitting or not. I do know that it can. It probably is. But the icon suggests it is not. Finally there are lots of extra stupid things. If I disconnect the DCM, the cars GPS stops working. That’s fine. But then my iPhone, when connected to the car, will use the broken signals from the cars broken GPS, and then it won’t know where it is! Also, I have to connect CarPlay by wire, not wireless. If I connect by wireless, the car will use the phone to transmit its telemetry!What a massive PITA!@zotnobot @isocat

       @paco @zotnobot @isocat IMO if you want to cut the car off do it completely, don't connect your phone to it at all.
