My prediction is they go back to making Golf Carts. The market never supported a working business model for EVs outside a very small niche (and expensive) group.
Truth is, without subsidies, the “family EV” is basically not profitable on a large scale.
I respectfully disagree. It's families in particular that can get practical use from an EV. I wouldn't get an EV as an only car, because there are some long trips that don't have plenty of fast chargers. Or perhaps a long trip in the north during the winter. Those are times a gas car is practically a must. Thus, families (i.e. needing two cars, not a single person needing just one car) are the ones for which one car being an EV might be having the best of both worlds (one EV and one gas car). The single people (read: need just one car) are the ones I think an EV would be a bad car for.
Even for families, I wouldn't get an EV unless you drive it plenty of miles with home charged miles. "Home charged" means don't live in an apartment where you can't set up a charger. So again, families are the best options for EV's because families are the ones more likely to be homeowners. And "plenty of miles" IMHO comes out to about 12K miles per year (the threshold where gas savings of an EV top the extra costs that come with an EV, at least that was the case 3 years ago when I researched it). My wife and I drive our EV 18K miles per year -- the gas savings and oil change savings is very significant. We no longer say "her car" and "his truck". Whichever one of us drives that day takes the EV to save on gas (unless of course it involves pickup chores).
“My prediction is they go back to making Golf Carts.”
I would say small commuter cars and hybrids. There would be a market and they can improve both over time expanding their market. Government mandates are never a good idea particularly to solve an imaginary crisis.
