Still waiting for the right moment to open my “Charge and Chill” in Indiana. It will be like an electrified Buc-ee’s, somewhere that you can comfortable hang out for a half hour or so. Games and arcade for kids/family, internet and working stations for the business traveler, a little cafe with fast casual meals and coffee, maybe even a dog park?
Most expensive is going to be the electrical infrastructure. If you find closed down supermarket with 1000-1200 service that can be refitted to help with the entertainment/food and used for your L3s this will help; you will need to get the money for local/state/fed governments to make it work and it will still cost a lot. As a stand-a-lone vs chain it get cost prohibitive but not impossible. Once you get an idea of cost, location, rebates and financing and you need to find a space let me know.
I’m sure there are plans for large private investment in this, just not yet, waiting for more EV’s on the road. I’ve read that the permits to get very high levels of current can be tedious. Maybe Elon will share some info on this
