Back on topic….. IMO I think we might easily see the full electrification of new cars by the end of this decade. IOW, fully EVs and hybrids. I am thinking world wide here, not just the USA. Or people might just keep their ICE engine cars running longer. They are doing that today as the price of both new and used cars has inflated to the point that spending $2500+ to keep the old clunker running another year or two is now a very reasonable decision. Economic Man strikes again!
In all reality, most Americans can't afford to buy an electric car and hybrids come with a premium cost adder. That won't change by the end of the decade due to high battery costs, unless "new" battery technology is developed. And that's been talked about for quite some time with no recent concrete results.
Also, many ICE vehicle uses don't convert well to battery due to size and end use. And there are a lot of them (buses, big trucks, construction equipment, aircraft, boats and ships, etc).
EV's work for small passenger vehicles and local delivery vans, and I see that continuing, but my lawn crew, hauling a trailer full of equipment in and heavy cuttings/tree stumps out, won't do it without his big diesel or gas powered truck. And his crew making minimum wage won't drive home in their $50,000 - $80,000 Tesla.
No manufacturer here in the states has come forward with a truly affordable EV in the $25 - 30 K range. I know the model 3 by Tesla claims to be close, but they mask the cost by subtracting the income tax credit (not everybody can use this) and then subtracting some fictitious savings on gasoline that's not offset by the cost of electricity needed to run the car.
GM's Bolt was a close candidate, but try to find one for under $40 K. And GM has decided they won't make them after 2023 as there is not enough profit in them. I have a friend who has a 2023 Bolt, and I have driven it. It's quite nice for the $43 K he paid for it. I would buy one if it was inexpensive enough. But the range is just slightly over 200 miles (on a good day with no hills).
So I'll stick with my 2021 Hyundai Tuscon SUV witch I just drove back and forth from Texas to Joplin, MO this last week averaging 31. 7 MPG @ 75 MPH most pf the time with the A/C blaring (hot here). It was 550 miles in each direction with one stop for fuel and a bathroom break. I can't give this car up as it fits my needs and is economical. Best run this year averaged 34+ MPG (Birmingham, AL to Atlanta, GA with a tail wind!).
