CCS infrastructure?

I thought the Bolt was maxed out at 50 kW DCFC. Even with the manual's numbers, it says 90 miles are added in 30 minutes. I assume after 30 minutes DCFC on the Bolt tapers off. So if 30 minutes is 90 miles, that's 90/238 = 37.8% battery added = 22.68 kW in 30 minutes. Ignoring tapering, in a full hour you theoretically could get 2 * 22.68kW = 45.38 kWh which is approx. the 50 kW charger limit for the Bolt I keep seeing everywhere online.

Wouldn't an 80 kW DCFC station mean that in an hour, it delivers 80 kW to a car that can handle it? So if the Bolt did allow for 30 mins of peak DCFC charging rate at 80 kW/hr, wouldn't that mean 40 kW could be delivered which is 2/3 * 238 mi = 158 mi delivered in 30 mins?

I say Elon further upset the established auto makers and start providing adapters (sell them or install them at the Tesla chargers) and allow credit card payments at the chargers. Then, charge non-Teslas a higher rate per kWh delivered but not as egregious as evGo or Greenlots. If this were possible, I'm sure many more people would take road trips along Tesla-covered routes knowing they can charge. Even at a higher rate, it's a once-in-a-while cost unless you road strip every weekend.
