Anyway, not building them because they might get used seems an odd trade off. The cost to build them is low at existing facilities, so it's not a zero sum game where adding one to a service center subtracts one from a highway rest stop.
If they put HPC, asside Superchargers, people can choose fast or fastest charge!
Would 4 hpc cost more than 4 superchargers?
I guess once the basics of a supercharger are installed, adding berths will cost +/- same as adding a hpc! no?
Actually I believe Superchargers are all Solar powered.
Not sure it works quite as well in places with less sunshine than California - maybe in Norway they will place the superchargers in locations suited to hydro rather than solar?
