That doesn't really surprise me.

Here in San Francisco some of the city transit system's bus tracking equipment that they use for real time arrival predictions was still using 2G when the 2G network shut down in 2017.

Then a different part of it was still using 3G when the 3G network shut down in 2022.



idk what about temporarily shutting down 1/2~2 day(s) per week for 2 months right before fully shutting down?

then we can know if something is affected by the full shutdown


That's called brownouts and incidentally is what OSM operations team did when disabling OAuth 1.

I was expecting you to say how SF train system is still run off floppy disks.

Is that why all the “next arrival time” displays on SF’s bus stops stopped working several years ago?
