The "miles per hour" charging rate is very misleading. Yes if you wanted to charge a bunch of Teslas to 20% capacity and swap them out after a few minutes each you'd get 1000 "miles charged per hour" But as the battery fills on each car, that rate drops substantially.

If only gas stations marketed their pumps like that. 10 gallons of gas can come out in 1.5 minutes in a Prius resulting in a fill rate of (500 miles range * 40 fill-ups per hour) = 20k mph! We won't consider the time it takes for the next user to get in and put the hose in because Tesla doesn't either.

I am a fan of EV vehicles as well but the long range fill up story is still not good.
