This is our household as well.
We are seeing 310*80% as real-world range on 80mph roadtrips.
This will obviously fall some during the winter (amount TBD), even in the South.
Combine the above with the fact that we really don't want to be running the battery too often in the 0-20% range nor in the 80-100% range, and for my household's use case the SR has never been in play, and the MR would not be in play either.
That said, I get the fact that the SR will be perfect for many people.
I do think there are plenty of first-time EV buyers who are thinking they will enjoy 220mi of real-world range from their SR and are going to get a rude awakening by the time they do 220*80%=175, minus buffer for 0-20%, minus winter temp impacts (or rainy weather impacts for that matter), and superchargers aren't perfectly placed and charge more slowly once above ~70% SOC, and the SR will not be a practical road trip car for anyone but the most patient of EV loyalists.
Use cases matter. A lot.
