Obviously everyone's use case is different.
The way I would frame it is this:
1. Your car has x range. Let's say 200 mi. or 321 km. And takes 1 hr. to charge. (Just for reference, my current car gets refilled with gas every 400 km. and takes 10ish minutes to do the task).
2. How long does it take you to travel that range in everyday life. For me, it would take about 2 weeks. But lets assume that its winter or I'm driving a lot and my time is cut in half, so I need a full charge every week.
3. Now I ask myself if there is anywhere in my driving schedule where I consistently spend about an hour in a place where there are chargers. The answer is, of course, I might go to Costco, the grocery store, home depot and the library In the course of a week. Of course partial charging is also an option, so two 30 min stays at any of the above also solves the issue.
So I'm covered for my average use case if charging at home isn't an option.
It is a smart question to ask, but it is actually pretty easy to answer if you think it through. Obviously there are a million and one use cases for a personal vehicle, but me and all my friends would be fine.
Even thinking back over the past year, including lots of outdoor activities into the backcountry in Canada, I have a hard time thinking of more than one trip that would have been different with an electric car (towing on backroads in the mountains. A corner case if ever there was one).
My theory is that charging infrastructure will all of a sudden become as necessary a commodity as parking. A restaurant that has a few chargers in the parking lot will attract more business, and I wouldn't be surprised if it also became a revenue stream as well.
