You're right, it's not nobody, but I strongly believe it's a rounding error to the broader population who will choose to drive the expensive car they paid for when they need to drive somewhere.Well that's just wrong on a lot of counts.
There's already some BEV owners renting cars for long trips. (Although more common is simply taking a different car they already own, as BEV owners tend to be on the well-off side due to their higher prices.)
There's already people not buying a BEV because it's not a good fit for them (particularly if they don't have an easy way to charge at home, which is the primary advantage of owning a BEV).
Doesn't mean many people don't use them on road trips. But saying "nobody is going to rent a car" is just wrong.
