Knowing that you want to be scrupulously accurate in all matters, I assume you will want to acknowledge in the future that your above sentence in no way describes the Tesla experience.
In the past two years I have taken ten of what I would call 'road trips' from Asheville, NC. The destinations were Charleston, New England, Nashville, Columbus twice, Cincinnati, Detroit, Austin, Orlando, and Denver. Virtually all this driving (actually Auto Pilot did most of the driving, which allowed me to drive much, much further and arrive much more relaxed) was on Interstates at speeds of 65-80 mph, regardless of temperature. Tesla Navigation plans the route, Super Charger stops and their current usage, and provides estimated charging time.
I can count on one hand the number of times I had to wait for a charger, and only once much past 5 minutes. Also, given the physics involved, you generally only charge to 80%, which takes approximately 20 minutes (during which time I relieve my 76 old bladder and catch up on the days events via the car's YouTube connection).
One person's experience. You're welcome.
