For me the source of range anxiety is not that I will not get to the next charger or that I will have to wait 30 minutes to charge. I'm worried that the charger will be broken. Chargers are complicated. So far I was not able to charge because:
- the charger was completely dead
- the charger repeatedly failed to establish connection with the car for unknown reason
- the entire infrastructure of the charger operator was down
- the Android app didn't work on GrapheneOS
- the charger was in use
- the charger was installed in a place without 4G coverage...
I would estimate that chargers work maybe 70-80% of the time. Having an app with live availability info helps but you really never know if you will be able to charge or not.
