Is there a practical way to block any outgoing communication and telemetry from getting sent? Like a Little Snitch but for your car?

Well, I removed the telematics module from my car. But it already stopped working because it was 3G only. The car was built in 2014, shipped with a 2G modem that was replaced at Ford's expense when 2G went offline shortly after the car was sold.
My other car with telematics was built in 2016 with a 3G modem that also no longer works.
I guess there's a silver lining to sunsetting 3G I hadn't considered. Thanks!
For my car (2024 GR Corolla) you can pull a fuse that goes to the telematics computer.
The car has a bad habit of calling the emergency hotline on a race track if you go over rumble strips (those painted red/white strips) because it shakes the car so violently I guess. Popping the fuse will make it stop happening.
On my 2021 Camry, the fuse is labeled `DCS` — the only caveat is, it disables the front-right tweeter (there is a bypass, but requires you to remove the front dashboard and install jumpers across the DCS connector).
Those are the two randomest things to couple together in a single fuse.

I remember reading on HN that someone found a sim card in their vehicle and took it out.
Presumably the new ones use an e-sim instead of a physical one.
I wonder if metal tape, used for ducting, would work.
Doubtful... BUT if you try, remember that most vehicles have dual antenna (one on top, one on bottom - for roll-overs).
It's easier to just disconnect both antenna from the modem OR disable power to it entirely.
