> Well, that's US. I am in much more densely populated Central Europe - several orders of magnitude compared to California.
The average population density of California is 250 per square mile, for Germany it's 620. Considerably less than one order of magnitude in difference.
> For most people here, workplace is 15-30 minutes walk/public transit away, that's not going to solve anything about car charging.
If people are not driving to work, their cars can charge at home during the day, so it's already solved.
> And there's not enough physical space for solar arrays of this size.
There most certainly is. People overestimate the required space to a ridiculous degree.
