@Sisko - DS9, you've completely missed the point and possibly misunderstood the basis of the requirement. The reason your analogy to the gas pumps is such a poor one is that the properties supporting those "filling stations" were designed and built from the get-go to meet that purpose. And were therefore designed to meet the space needs for both "dedicated-use" gas pumps (i.e. the business purpose) AND separate general parking spaces (i.e. the zoning requirement). But, make no mistake, they had to meet the parking requirements to get zoning approval prior to beginning construction. In the EV case, the charging stations are a retrofit compromise. They aren't being placed in
unallocated space on clean slate property development. They are being put in spaces that the site development designs had already allocated for a separate/distinct, and required, purpose--i.e. parking spaces. Of course no one would design a gas station where the spots at the pump were allocated to also be used as general parking spaces. That would be a terrible design. And if someone were likewise building a bespoke EV charging plaza on
undeveloped land, they could make every stall permanently reserved only for charging use if they wished. But THAT'S NOT WHAT'S HAPPENING. Charging stations are being shoe-horned into an already completed design--often one where the number of "free" parking spaces over the minimum for zoning approval is very low if not already zero or negative--and where they therefore have to "share" the space to meet multiple uses, because otherwise they won't be allowed to build the charging stations at all. It's either share or get nothing because parking is required and charging stations aren't.
It would be nice to have all EVCS be permanently dedicated stalls, but that just doesn't reflect their compromise reality.
