Personally, I think we should go the Fallout route and have nuclear-powered cars. Submarines can do it, so we can too!
But seriously, we should've had hybrid-almost-everything 10, 15, 20 years ago. The tech was always there for that. We intentionally went against it, especially in this country in particular, because so many people had to go out of their way to demonize the goddamn Prius. Everyone just had to roll coal on Prius owners and label them all gay for 15 years so everyone else got afraid of advancing the world of hybrids for no actual reason at all. Set us back literally decades for nothing. There is some room to produce and sell more hybrids, not a lot, but some. I suspect they aren't being produced to demand somewhat intentionally to keep prices up, as opposed to BEVs, which were being pumped out rapidly to match massive government discounts on them in the same time span. Mavericks sold a grand total of under 100,000 Mavericks last year -- not all of which were hybrids, as they offer ICE drivetrains also. They sold over 400,000 F-150s for comparison. The Maverick is outsold by the Escape and Explorer. It's far from a top seller, but the demand for the product is there (both it being a hybrid, and it being just a small truck).
I know for my particular lifestyle, I could go buy a plug-in hybrid tomorrow and be covered for pretty much every facet of my life. It would be weeks, possibly months between me stopping at a gas station with one of those as the vast majority of my driving could and would be done on the battery. Can't do that even with a traditional hybrid.
