This is being addressed, though slower than it should be. A friend in Brighton positively lured me to visit her with a photo of the 4 kw kerbside charger outside her house. It's one of several in that and surrounding streets. (She doesn't have a car at all, and that's why I was being lured, to take her on a few jaunts.) The provision seems adequate at the moment. Drivers of ICE vehicles were generally leaving the parking space clear although there was no sign mandating that, and one EV driver who arrived in hope just as I was plugging in said, "no worries, there's another one just round the corner."
The fact is that every car is parked somewhere overnight. The challenge is to create enough opportunities that when the car needs to be charged the driver can access a suitably-equipped parking space for the night, whether it's kerbside or in a residential car park or wherever. In addition many visitor attractions are now seeing the benefit of providing AC charging spaces in their car parks so that people without home charging can leave the venue with a full charge. Most of these are considerably cheaper than the big DC public chargers.
They're also frequently vacant, and that last post encapsulates why. People are reluctant to buy an EV if they don't have home charging, because they are (often unrealistically) pessimistic about how they will charge their car. People with home charging won't use destination chargers most of the time because they're more expensive than home charging. So the destination chargers, which make life so much easier for those without, are seen to be empty and providers question the utility of installing more.
