70mph is the upper end of the sweet spot for Tesla distance driving. I lived in Chicago for a decade and had a Model 3 for the majority of that (purchased it in 2018 new). From our house in Chicago to our family's house in Kentucky, it was 385 miles door to door. We'd stop in Indianapolis (or Lafayette, IN) and grab a bite to eat, stretch our legs, and use the restroom. It would always be done charging before we were finished eating, so no big deal at all. We've since purchased a Tesla Model Y and have done many road trips. I'm hoping to get the Cybertruck in the next year or so with the range extender. I do have a farm and plan on using it to haul stuff, but with 470 miles of range, we can drive generally longer than I'd ever want to with two kids and go camping.
