Many, many houses do not have anything other than on-street parking here. Since 2012 I've lived in 5 houses, and three of them had no driveway. I'm currently buying a house which has no drive way, with no way of fitting one. Apparently 1/3 houses have only on street parking. Unless they also provide huge, huge grants to rapidly implement dense onstreet charging, and fast, this is a pipedream and will end up getting pushed back.
Edit: To evaluate the scale of how difficult it is to implement on street parking - go and have a look out of your own window in a built up area and count the number of lamp posts and the corresponding number of cars. Right now (9:35am), in a pretty built up area, I can see three lamp posts on my own street, and eighteen cars parked on the road. One of those lamp posts is located where it's illegal to park because of double yellow lines. I currently live in a rented flat at the moment, and that has another 25 car parking spaces. To get charging points located there would require a number of disparately located and willing landlords to agree to wire up the car park for electric charging too.
