Inconsiderate users is an issue, and will increase once EVs become more popular.
One thing I noticed with the Tesla charging network is they seem to be unattended. I would have thought a cafe onsite, even if it were a touch overpriced for the captive market, would be a winner. Give the punters something to do for their twenty minutes, and the profits from the cafe could make the "free charging for life" sustainable.
It would seem they haven't gone down that route but if charging stations are placed well in general, the idea of stopping for a coffee every couple of hours on long trips makes a 200k range quite manageable. Perhaps Z and BP need to get in on the action as they have the cafe's with good hours already in place.
