Several Target stores near me have charging stations now. 7/11 starting to put in some as well. Some companies have put in charging spots for employees. Even our library has 3 charging parking slots.
We have some spaces with Chargepoint chargers where I work, and they are powered by several electrical boxes that are each about half as big as a parking space. There is some serious juice being pushed through those -- and the Chargepoint chargers are only serving 30-40 amps, which is about the same as a home charger and nowhere near what a Telsa Supercharger delivers.
This kind of stuff is not trivial, or cheap. Tesla spent a lot of money to get their network to where it is.
