In a worst case scenario: US Invasion. What device could the US government simply force to stop working in Canada that would cause the most chaos (e.g: brick all iPhones)? (lemmy.ca)

What products are most at risk. What are easiest to replace to reduce risk? Hardest to replace?

iPhones wouldn't be that bad I don't think. Cell/internet infrastructure would be much worse.

American vehicles would be harder to replace. We know Teslas can and have been remotely disabled in places where Tesla didn't want them being used. I'd be surprised if the big three didn't have remote killswitches in their vehicles already.

It's not even a secret. Almost all modern cars do as part of remote service packages. It's what let's you ask them to unlock your car, do remote start via a phone app, or let's the police request a remote shutdown of a stolen car.

Fix that by disconnecting the cellular antenna in the car and the telematics unit. You may need a bypass harness on some modern cars that "responds" to connectivity pings in the car's canbus, but otherwise you can't kill what's not connected. :3
