The piece of the puzzle that
The piece of the puzzle that you seem to be missing is that if time is a factor, EV's don't get fully charged. The last 1% of charge can take as long as the first 50%. To make best time on a road trip, EV drivers typically charge to anything from 40% to 70%, unless they're busy doing something else. If you're following proper etiquette, you shouldn't charge to more than 80% at a busy charger unless you absolutely need it to reach the next charger. Semi drivers will probably use charge stops for their 30 minute breaks.
