Having an EV requires charging at home. People that can't charge at home don't buy an EV. People that would charge in a parking lot don't have an EV.
Public charging has really stagnated in the last 5 years.
If it were me I’d even try to sell them washer fluid and other road supplies.
I think there are also a significant number of EV owners who almost exclusively use public DC fast charging. If there are enough fast chargers around, you can treat an EV similarly to an ICE car - drive it til its mostly empty then fill it up.
Relevant article from today referencing a recent MIT study.
As someone who owns multiple EVs, it's about the fact that you are much more likely to go to a business within probably 1000ft of the charger. The chargers are also frequently very busy. I 100% go to a ton a businesses that I wouldn't otherwise simply because they are located near the charger. Convenience is king
I’d never stopped in one of those places in my life.
