That's the thing about cars: their real test (or importance) is not the 90% of the time spent in the "happy path" (short, planned drives after a full night charge). It's to address those edge but critical cases - long trips, unexpected drives, off-the-beaten-path routes.

Another thing rarely raised is the correlated nature of traffic issues. Charging is fine now, mostly because it seems there is a huge over-provisioning of chargers compared to EVs on the road. What happens with busy days? An evacuation order sending 1M people on the same route at the same time? For ICEV there is an easy solution. Not for EVs.
