Here's some actual data from reality, using a (rare) 50kW DCFC. Sure looks like 3 hrs on the road and an hour-and-a-half charging to me. Call it a 2:1 ratio of roadtime:chargetime. If 80kW chargers existed, they could presumably raise the ratio to 3:1.

Not my idea of a relaxing road trip, given the anxiety as to whether a planned charger will actually work when you get there.
