Recent model toyota vehicles come with a "telematics" unit with a built-in SIM card that sends GPS data, driving data, video from the front camera, etc. to Toyota and the "agreement" in the manual says they can do ~whatever they want with it.
If you power down the telematics module (by removing the fuse), the carplay microphone doesn't work (because the microphone runs through the telematics module).
If you remove or cut the antenna on the module, you get a Check Engine light, which means you can't register your vehicle in many states.
You have to call toyota, ask them to turn off all the data collection, and hope they really do it.
It's really sad to see a historically very good car company fall so far.
