How do they make their money

as a professional diesel mechanic for a small chain of midwest shops, this "telematics" feature is on long-haul trucks as well as tractors (john deer is notorious for using it to send mail marketing about services.)

generally its not hard to disable.

- identify the telematics module in your car - pull the fuse (not always an option, sometimes this disables bluetooth)

- alternatively: identify the 1-2 SMC connectors on the telematics device. this is the LTE and low/alt channel for the cellular communications. disconnect these 1-2 connectors and connect the ports instead to a 50 ohm terminator. the vehicle will simply continue to collect data but never be able to send it anywhere. the system will assume it just cant find a tower.

Ok stop with the panicking.

What's wrong with GPS in vehicles? If it's not connected to the internet, there is no issue.

What's wrong with playing music from the phone on Bluetooth or Aux? Did you also know you can ride a horse instead of a car?

Bluetooth and WiFi isn't running if you turned them off. Bluetooth also isn't really used for tracking unless someone is looking for you or you're part of some service like AirTags.

> Ignore your car's complaints and error messages. Did you know Orange dash error lights are non critical?

What? Worse advice out there regarding cars.

I see absolutely no reason not to completely unplug the cellular modem. The only thing that would stop me is an annoying error message or warning light in the gauge cluster. My car does not display any of these, but unplugging the modem results in losing the right speaker and microphone, unless a bypass harness is used.

With all the back and forth over the props, also with Ridley Scott scrapping loads of spaceship footage in order to reshoot everything after repainting the models, I get the impression that communication was quite bad in the production. I'm sure we've all encountered this in industry to some degree but having months of work tossed because it ain't look right must sting somewhat.
