There's lots of overnight street parking in the bay area, but there are lots of other opportunities to charge. The actual hard case is someone that drives a significant amount during the day, doesn't have charging at work, and can't have charging overnight. Here really the only option is DC fast charging.
However, this is a reasonable rare circumstance, and it's only getting easier to charge.
One potential source of traffic in LA that will be tough to meet with an EV solution as currently offered is the 'handyman' persona. Either legitimate businessmen such as plumbers or landscapers and what not, or those people who extend their truck beds with plywood to stack the scrap as high as the freeway bridges will let them, either way all of these groups of people are driving all day, at all hours, to oddball places all over the place, and are in need of cargo space. The job site of the day might not have reliable drinking water let alone a supercharger for you to tap into.
However, this is a reasonable rare circumstance, and it's only getting easier to charge.
