Or inexpensive (to install, not to use) and widespread charging becomes available in most locations.

A normal 13A socket will charge my Leaf in about 12 hours. The 8 hours of charge I’d get from plugging in at a parking bay during work hours would likely be enough for most people, but we have no current infrastructure for billing people at that scale (although I imagine it could easily be developed, still a massive undertaking to roll out widely in cities though).

We’d also need to be able to provide the massive increases in grid energy that would be required for that. Nuclear seems like it would be a good use case for this but that still seems like it would be a tough sell, even now.
