Another scenario is that you make a round trip on a day, coming back home at night, without necessarily staying at places that have a charger. So you'll be making stops in any case, but not (necessarily) next to an available charger. Or even on a one way trip you'd like to (also) stop at a place without charger. In either case, you don't need additional resting.
I agree that a Model S could make much better use of 50 kW chargers than a Leaf, and it may be enough for you as a dedicated EV enthusiast. But when you make a longer trip as an average person, you want the charging to take away as little as possible from the few hours remaining in your day. You'll want to decide for yourself where to spend that hour, or 40 minutes. You won't be thinking "I'll have full dinner here, instead of where I am going, so that I can support EVs". You'll be frustrated that you have no choice. You'll be thinking "I wish I had an ICE, so I could finish my trip like everyone else".
And yes, for getting mainstream acceptance for "EVs are the future", to get car companies to support battery technology instead of hydrogen, even 90kW may be slow. But, at least, much closer to happiness, than 50 kW.
