@roblab, so glad you know what works best for me and my family. We took the best vehicle for the trip, period.
RX getting 25 MPG is impressive to me because it was carrying a full load, travelled at 80 MPH speed limits, with elevation gain, and still
exceeded its EPA rating. Try packing any Tesla full and drive 80 MPH... your 100+ MPGe rating goes out the window.
I actually enjoy the act of driving and chose not to fly, especially during a pandemic. You can go trap yourself in a plane with hundreds of others breathing the same recycled air but I'd rather not.
To your second point, no, not every stop needed a gas station. We just needed a potty stop. If I did pump gas, you do realize pumps have a handle lock so I can still sit comfortably inside the car while it fills up, right? EVs are not the only vehicle where you can sit inside while you wait.
Thirdly, you're going off of spec sheet for cubic storage rather than taking into account the shape of storage. I consider myself a master organizer too, squeezing more into the refrigerator or car than my wife thinks is possible. I parked both cars in the driveway and literally tried to pack the same amount into the S and couldn't do it. On top of that, the S is still lacking a spare tire! (Side note: the RX also has a secret compartment beneath the cargo floor that isn't accounted for in those publicized cargo specs you quote.)
The S is a great car and I would have loved to take it on this roadtrip, but it didn't work out and I didn't need to force the issue like you have the need to. Try to keep an open mind next time. An EV is not always the best choice and that's okay. I want to help the environment too and am making progress each day I drive the S. Yea, I still drive an ICE, but I drive one ICE instead of two previously so get off your high horse.
