Can we prevent cars from sending data to servers if we remove their antennae? (lemmy.world)

I don't know anything about cars.

Now that we have established that cars seriously undermine our privacy (look at the flurry of posts in this community in the last few hours), what can we do about it?

From a networking POV, if you remove the ability to connect to the Internet, it doesn't matter what the car is recording as long as you can ensure there is no physical tampering. Depending on who you are, this is a good idea, and doable for the most part (very few people have the technical knowledge to pull out the right chip from a car).

So, how do we achieve this? I implore the community to invite mechanical/car engineers who can help us on this matter, and to form methods to prevent vehicles from accessing the Internet without express consent from the user.

Thanks!

So only thing is they might just store all the data locally and send it when they get reception again. Microsoft Word used to do this with "Aria"

Do you not understand what a Faraday Cage is or does? It literally blocks radio frequencies.

Cover the module in a metal screen, block any and all data transmission and reception, without even altering the electronics.

And the vehicle ain't got much other choice but to keep functioning as expected anyways, as it's expected to have signal loss at times anyways.

Edit: If you think losing internet connection is gonna break your vehicle, well God forbid you ever drive through a tunnel...

I think they mean it would cache the data and release it if you ever had to remove the screen for whatever reason.

Driving through a tunnel is a short break in connectivity. These things are probably built in such a way that they'll brick after not being able to connect for an extended period since not working due to a short disconnect would give the brand a bad reputation after happening a few times.

My concern is that Faraday cages have limitations and you should think about mitigations

Seal it in lead then, what you want from me?

I'm just spitballing a possible solution here..
