Yup. I own a Tesla and it's been a great car. I charge it at home, and I know how the supercharging network works.
I've been OFFERED electric rentals in:
* Tromsø Norway (on a roadtrip through the Lofoten)
* Nelson NZ
* Brisbane AU
The reality is, when I rent a car on vacation, I'm typically doing more miles per day than when I'm at home. That's because I'm not sitting at work 9 hours a day! Plus, I don't know their charging situation. Even if it WAS Tesla, no doubt these places have fewer Superchargers per capita than California (even though of course Norway has a TON of good EV charging). I have no idea if I can charge at my (multiple!) homes throughout the trip.
I'm already dealing with the cognitive load of a different country, a different currency, often a foreign language, different driving standards (maybe on the other side of the road). Finding places to stay and eat. I don't need one more chore!
To put it simply: An EV is more convenient as our primary car, full stop. An EV would be less convenient as a rental car while on vacation.
