You’re still missing the point. Are you really claiming that most people who go on long trips once a year haven’t thought about renting or flying? Or that they’re unaware of those alternatives? They’re reasonable alternatives even with an owned ICE car - do you want to throw 3,000+ miles on your car vs a rental?

Presumably there’s reasons they drive an owned car vs renting or flying already.

Look, let me try an analogy I’ve beaten my head against for a decade or more - do you use Windows on your computer? Why haven’t you switched to Linux? It’s better in almost every way - it’s free, it’s user controlled, it doesn’t break / have patches forcing reboots monthly, it runs on older computers better for longer, etc etc etc. Now think of why you (probably) don’t use Linux. It doesn’t run Microsoft Office. It doesn’t run your games. It doesn’t do whatever that Windows does. Is my response that - “well, you shouldn’t play games on your PC, you should have a game console, or rent time via remote control, or just you know - why are playing games important” actually compelling to you? Now apply that to cars and driving long distances.
