It's unrealistic to switch everyone to EVs right now. But many two car households could reasonable have one EV and one ICE car. The Chevrolet Volt was pretty much perfect for the current situation: most commuting would happen on the battery but the extra long trips would switch over to gas.
What happens to those people when the cost of gas is sky high because economies of scale are completely gone and it's a niche product?
(Serious answer: gas will be subsidized, just like everything else up there.)
If you have no charging at home but a walkable charger nearby, with two EVs, you can drive the second one to your vehicle that is already at a charge station, and trade off, driving the first one home and leaving the second one to charge. Then trade off again later. With an ICE car as the second car, you would either do more walking (nothing wrong with that, sure, but it takes time) or you need a second driver.
You’re possibly falling into the trap of thinking EVs are hard to use for long distance road trips. Depends on which EV though. Not true for at least one brand.
I see a lot of ICE drivers giving an EV driver a ride to the charger. For example, husband wife couples.
If they had two EVs in their (multi person, ok?) household, then the ICE driving person would not have to spend their time being a chauffeur, because the EV driver could just drive the second EV to the charger and leave it there charging.
It feels like you have a half thought out point. Sure it can work, but I think anyone in that situation would discover it is really inconvenient in practice.
It means if you have a 10 minute walk to the charger, you only have to do that walk once when you drop off for the first charge, and once when you pick up for the last charge. That can save a lot of time.
I don't know whether gas is subsidized or not, but if it is, I agree, remove the subsidy!
Same as corn, dairy, etc...
