I don't know about you, but I just can't wait to charge at 1/3rd the speed of a supercharger at 1/3rd of the national locations. There's nothing better than spending an hour charging inside a dealership parking lot for every two hours of driving. I also cannot wait to fight over other EV drivers over the 1-2 slots that will exist at each of these locations as opposed to the 4-16+ slots that exist at every supercharger.
You're also assuming that the Supercharger network will never have a next generation, when they've long been rolling out liquid-cooled cables to prepare for upgraded charging speeds.
You're also assuming that a single company will roll out a comprehensive, cohesive well-supported CCS network suddenly springing out of existence of the loose consortium of dealer-run CCS chargers available now combined with random pay-per-use chargers from five different companies. Or you're assuming the US government is run entirely by EV-friendly politicians, which is perhaps even more unbelievable than a legacy automaker starting a competitive charging network.
Please, please don't insult Tesla by even remotely comparing CCS or chademo to the supercharger network. It's night and day, as big a difference of Mirai versus a Model S.
