alt Hacker NewsIs there usually a fuse that just turns off the telemetry? I would be surprised if that is the case. I could see the design being "if you turn this fuse off to turn off telemetry, you'll also lose these functions: ..." and if they did it "right" they'd make the car non-functional.
My car is from 2011 and I do wonder if there is any telemetry in it.

Probably has something to do with the fact that car companies are obsessed with having the thing modularized, each module needing a fuse.
There’s probably a fuse to turn off the cellular radio that transmits the data. Whether that’s all it covers may vary from car to car. Or in some models it’s probably possible to just disconnect the radio entirely.
Telemetry is usually a standalone module. Heres one off a 26 Hyundai Palisade -- Telematics (DCU) Part num: 96510P9100 firmware (OTA updatable) 01F.7.CAN.3.000.18.714.9
Its only job is to detect harsh acceleration and brake events. Probably being sold to your insurer.
Yeah an electrical fuse for telemetry seems really odd. Even without malice it would be strange if disconnecting power to some part of the computer only affected telemetry.
I could see a fuse for cellular comms, be presumably that would also disable maps, contacting emergency services in an accident, etc. which might be an acceptable tradeoff.
