His use case for the Odyssey must be atypical from what I've seen, that is, it's used mostly for short local trips. What most people I know use their minivans for is that, plus family road trips. Not really an option with the Tesla.
There are a fair number of people who don't do road trips. It's not a universal thing.
For those who do, how often do they take them? If it's a once-a-year thing, you can rent something more suitable for fairly low cost. I see a lot of people basing their car buying decisions on activities they do once or twice a year and it puzzles me.
Finally, not all road trips are created equal. If you're regularly driving across Montana, the Tesla is probably not for you. For me, where my road trips consist of occasional trips from DC to NYC or Virginia Beach, the supercharger network means the Tesla would be fine.
Feel free to play with the annual mileage figures on the model. For my family's situation, I played around with it with mostly either 12K or 15K annual miles.
