Yeah exactly, with a car I would no longer be expecting any type of privacy, sadly. Here in Holland we must even have a mobile phone module in every car so it can call the emergencies in case of a crash.

It’s all of the EU. It’s literally illegal to sell new cars without a radio transceiver in them.

  But is it illegal to personally disable it?

    Nope.

    No but it often involves voiding warranty and/or labor-intensive, really annoying work to access something you can disable.

      On Toyotas, you simply remove a fuse [which can be re-installed].

        I can assure you this is not the case with all Toyota models or even most. It's often integrated into the radio instead of a separate module, or simply not on a dedicated fuse, but sometimes it is. Disabling it can also lose other features of the car such as navigation, remote start, the Bluetooth mic, or the mandatory eCall feature if you're in the EU. https://www.toyotanation.com/threads/wiring-diagram-for-disabling-dcm-functionality.1787352/ https://www.toyotanation.com/threads/wiring-diagram-for-disa... https://www.tundras.com/threads/dcm-how-to-remove-completly-to-stop-toyota-collecting-data.157659/ https://www.tundras.com/threads/dcm-how-to-remove-completly-... https://forum.ih8mud.com/threads/permanently-disable-telemetry-data-transmission-from-16-200s.1347480/ https://forum.ih8mud.com/threads/permanently-disable-telemet... https://www.toyotanation.com/threads/disabling-the-dcm-in-my-2023-corolla-le.1748448/ https://www.toyotanation.com/threads/disabling-the-dcm-in-my...

        On all 2016+ US Toyotas, removing the fuse labeled "DCM" will disable the following: •) Wireless communications module (including OnStar and telemetrics) •) Front passenger dashboard speaker (there is an easy bypass to re-enable, but must open dashboard — in which case just remove the entire module!)

I'm in two minds about this. Yes, there are severe privacy implications. But also this happened, just a couple of hour's drive from where I live, about ten years ago: https://www.bbc.co.uk/news/uk-scotland-tayside-central-33505854 https://www.bbc.co.uk/news/uk-scotland-tayside-central-33505... and similar things have happened about once a year ever since. Now in the news article I linked to a huge part of the problem was that the police didn't follow it up correctly, went to where the accident had been reported rather than where it had occurred, didn't see anything, and then gave up. But if the car had rung from where it had actually crashed then the incident would have EISEC[1] data tagged to it, which would have given them actual co-ordinates to hit.
