If you need to drive a bus into a tunnel to look for security threats, you already failed completely.
No government needs backdoors to shutdown these systems. You need a tourist and a funny hat.
Oslo's busses are electric and their charging stations are completely insecure, not even a fence. If I wanted to cripple Oslo's busses, I'd visit there driving an electrician's van one day with a gum to take the impression of the "lock" on the chargers. It's more of a security screw than a lock. I'd come back a day later and photograph the electronics. A few days later, I'd return with a circuit board capable of remotely shorting the contactor and also a component contains a corrosive that can be triggered to spray. I'd use a simple nbiot module with esim. Just label everything as Schneider Electric and it will be invisible.
Why sabotage the busses?
You can easily replace busses. The charging infrastructure is far more attractive and easier.
