I'll suggest that to her.
I've noticed ChargePoint Scotland has an interesting strategy in the villages. Smaller places (like here) have a single three-connector charger, only one car being able to use it at once. Mostly people use the rapid-charge facility, especially because there is a time limit (at 55 minutes they start fining you). However the type 2 lead is there, and someone who has charged to capacity on the rapid charger has the opportunity (after the 90-minute no-return period) of coming back for another 55-minute session on that. This seems adequate as the charger is frequently vacant, and I've seldom seen a vehicle waiting for someone else to finish. However in larger villages they add a two-connector type 2 separately, which I presume has a longer time limit. I've even seen places with two of the triple-connector chargers and two type 2 chargers (giving four connectors). Theoretically six cars could be charging at once, two with the potential for rapid charging.
This seems to work, providing DC facilities for anyone who needs a quick charge - either local or passing through - along with the ability to allow your car to balance-charge. I think a lot more residential areas could copy this. People without home charging facilities don't just need a type 2, which they'd be occupying for hours and if it wasn't very close to home they'd be twiddling their thumbs for a ridiculously long time, they need rapid chargers to take on a decent amount of charge in a reasonable time.
In areas where there are a lot of terraced houses and flats, unless it's possible to provide everyone with a long-stay (preferably overnight) type 2 charger within reasonable walking distance of home, they really need to install DC chargers as well. A visit to a DC charger while you're shopping, with the ability to leave the car on an AC charger sometimes when it's already at a high SoC is what's needed.
