At this point it is really tough to find devices that don't leak data like a sieve.
I recently bought a car, and could not find one without a cellular modem and microphones. Removing the modem voids the warranty. The period where you can opt out is mostly over.
The Magnuson–Moss Warranty Act of 1975 ensures that’s not the case in the US. I suspect something similar is true in EU.
For the manufacturer to avoid a warranty claim due to a modification or aftermarket part, they must show that the defect was linked to the part or modification.
They might have to show that it was caused by, but in any case, if your paint fails prematurely, they can’t say your warranty is void because you disabled the cell connection.
To get 5 stars by EuroNCAP (and AFAIK EU law demands it too) the car have to call 911/112 automatically if it detect a crash. I doubt you can remove telemetry without also disabling this. If you do the car is illegal.
Interesting point. I wonder if an insurance company can argue the modification made the car lose the safety certification, and in effect the user made the car more dangerous by removing the SIM card, and that it would not pay out for injuries sustained in a crash.
Because it is probably part of the vehicle type approval, it would be a modification that needs to be authorized by whatever institution does that in your country.
Otherwise it is probably mostly equal to driving without registration. It may not be a felony, but it will be fined.
Given what I see driving around on US roads, there is epsilon-squared chance this would be found let alone fined here. (I’m also not nearly convinced that it’s even illegal in my state and likely not so in any of them, especially given that my car had a dealer service to remove the SIM card as a recall item.)
It definitely wouldn't be illegal to remove a vehicle's cell modem from your own car in the US. The US is very friendly to vehicle modifications compared to much of the world. At a federal level, pretty much the only thing you cannot do to your own vehicle is remove emission equipment. The US does not even have universal requirements for insurance or safety inspections. And even in the states that do have safety inspections, there are typically very few pieces of safety equipment that are required.
Theoretically illegal perhaps but I'd be very very surprised if this ever actually gets picked up by anyone even on an annual roadworthiness inspection. Maybe during some OEM servicing but then again maybe not.
