eCall mustn't be active until an accident occurs. The lawful interception lobby tried hard to turn every car into a free data point they could sell to the government, but their efforts have failed.

Last I heard they've shifted their efforts to making remote activation of on-board cameras part of the 5/6G smart car bullshit (which will of course be part of road safety requirments not long after).

No, that's not correct. The eCall spec requires self-checks that include registering with the network on at least every ignition.

However, more importantly, it means you can't lawfully disable the modem that the manufacturer uses for its own telemetry.
