Here in Estonia, you sometimes wait for a ChaDemo cable to become available.
The operators of charger networks forbid hitting the red button (emergency disconnect) under any conditions unless it’s an emergency.
There’s a silent agreement among drivers that lack of charging opportunities is an emergency. :D If the other guy is not present and their battery has reached 80% or more (charging has slowed to a trickle and they have enough range to drive), it’s considered OK to hit the red button and hijack the cable.
But alas, some cars (guess which, the ones without door handles, specially designed for suicidal drivers) sometimes won’t release the cable.
You also frequently call customer support to restart chargers and watch Linux boot messages scroll by, and complain until blue in the face about specific chargers that stop working for some specific cars in cold weather.
In short, it’s pretty close to a mess. :o
In case humanity forgets about how to make CPUs, some folks would still remember how to make stateful relays, magnetic core memory, punch cards and pneumatic logic valves.
It would take a bit of time from there back to a CPU.
