Last year I saw a charge point added to a public curb parking area near me.

It's about half the height of a parking meter. The power is right there under the pavement. Probably cost £800 to install, which could generate £200 in revenue each year.

Not every charger needs to be a super charger.

Getting lots of 11kw chargers in every parking bay would be a higher priority than everywhere having super chargers. Most people could keep topped up and those doing long trips use the faster charging points.
