I don't really think we're through all of the low hanging fruit. There are a lot of single family home dwellers who have yet to buy EVs. Just drive around a residential suburban neighborhood and you'll still se a LOT of CV cars in the driveways and garages (with the doors open).
And most will have valid reasons for not having made the switch, whether they be financial or practical. After their house, a car is typically the most expensive item someone will buy (and if they rent, it's the most expensive), so they want it to be right, and they don't change on a whim. In the ICE world you can pick exactly the vehicle type you want/need - roadster, coupe, sedan, station wagon, mini-van, SUV - and then decide between gas, diesel or, increasingly, hybrid for the powertrain, but if you want full EV your choices are still limited and compromised.
One other thing: in some parts of the demographic, I suspect an aversion to the "iPad-on-wheels" approach to driver controls might play no small part - I still have to remind my mother how to copy/paste or forward email every few weeks, but not how to turn on the heated seats or tune the radio in her ICE car...
I'm a city dweller who doesn't have access to a home based charger. Fortunately I do have access to about 8 level 2 chargers (30A 220V) a little over a block from my house. We have two Teslas and typically charge 1 to 2 times a week for our pattern of usage. It's not the best but it definitely works.
I'm likewise a city dweller without the possibility of home charging. However, my city has perhaps a total 30 public charging points, spread across the carparks of the out-of-town retail parks, only a handful of which could be called "fast". Even better, most of the carparks use ANPR to limit your stay to 2 hours, so even if you can get a working bay, you'd get barely enough juice to cover the journey.
We do need more city charging options and more curbside charging to complete the transition to be sure, but there are places that are making it happen
They did dig up one corner of one of the carparks last year, did a load of cabling and groundwork, and I thought "Great, they're putting in dozens of EV chargers!"
