Just look at the number of pickup trucks there are, with empty (even pristine) beds. Nobody is hauling stuff most of the time, but they got a vehicle that can.
I think EVs make a great second car. I drive a Tesla, my wife drives a Bolt, and we have an F250 for towing the travel trailer, hauling household stuff around, or going somewhere that charging infrastructure is going to be inadequate (haven't really run into that yet, but the pickup is our catch-all). I can't see going back to ICE cars as daily drivers, but it'll be quite a while before we don't have at least one in our household. Especially as long as we continue to own the RV.
Or, rather: a small enthusiast minority gets two cars, generates the critical mass required to build charging infrastructure etc., then everybody can switch directly to an electric when it becomes convenient for them.
