I agree with your logic. It makes perfect sense to rent a vehicle for edge cases.

However, I disagree that you’re going to encourage mass adoption by asking people to change their lifestyle. A large amount of the US population views their vehicle as more than a tool to get to and from work. It’s an extension of their personality. Road trips might be part of that personality.

They’re sold on the marketing ideals of luxury, comfort, or adventure. They buy accessories for these vehicles like roof-racks for their luggage or campers/trailers to help them travel across the country while keeping that comfort of home. Tens of thousands of campers are still sold in the U.S. every year and EV’s are a nonstarter for towing more than 75 miles.

No one enjoys renting an unfamiliar Honda CR-V where the seat doesn’t feel quite right for long periods of time, there’s something sticky on the shift handle, the previous driver smoked in it, and you hear a plastic creaking sound coming from the back seat. You can’t quite figure out from where and it’s driving you insane.

Until EV’s can match the convenience and capability of ICE vehicles, adoption is going to be limited.
