This is it - even a highly available charging network only lightly alleviates range anxiety, as the other portion is the time it takes to charge up. If I can drive for 600+ miles on a single charge, the vast majority of my trips are covered, even round-trips. But sitting around waiting 30m to charge gets annoying every several hours, even if I can find a working station.
So.. wouldn't increasing overall range be the "one thing" you could do to actually improve this?
