I don't agree with your speculation for a couple of reasons, primarily:
- 90% of EV charging is done at home, meaning that even when all cars are EV, there will be an order of magnitude less usage of the public infrastructure.
- EV infrastructure does not require employees on site so it is not beholden to the same 'service center' economic model premised upon selling snacks and becoming defacto grocery stores for impoverished locals.
But also, EV charging stations are purposely located in existing commercial areas like malls, hotels, grocery stores, strip malls, etc. whose bathrooms are supported by businesses with a much bigger reputation to uphold than one whose customer loyalty is fundamentally linked to being 3 cents cheaper than the identical building across the street.
