The "extreme" rarity you claim for charging stations is a myth, possibly propagated by the petrol industry. Plugshare offers accurate information regarding the location of charging stations (https://www.plugshare.com/). And the cool thing about that is there are both commercial and home/ office stations, with more coming online all the time. It's kinda good that EM bobbled the supercharger thing, so it encourages more groups to start providing chargers. The great thing about Plugshare and ABRP (abetterrouteplanner.com/) is that it makes it very easy to see and plan for your next charge. Tho' I do agree that the way to go is make the E-charging cheaper, not to make the petrol more expensive, yet.
