Battery tech may see some breakthroughs, but as of today, given the current charging infrastructure, IMHO, if you want one vehicle, a hybrid has some advantages. I own the i3 that I use most of the time. But, when I do need to go somewhere further than it can reasonably take me, an ICE, or preferably a more efficient hybrid has some significant advantages. One with enough battery capacity to handle the day-to-day operations without running the ICE is my goal, at least until the charging network and battery tech improves.
A huge battery today just takes too long to recharge if you need to put lots of miles under your tires in a day, and a small one means stopping way too often. While hydrogen has the energy density, it's still not a viable option as there's only a few places in the whole country where you can fill one up. Flow batteries may offer some neat options for a fast refill, but again, infrastructure and getting them ready for prime time is going to take awhile.
We're in a period of transition. If you can afford more than one car, you may be able to pick the best one for the job, but there is not one solution today that fills all needs. Admittedly, carrying around the extra hardware for a hybrid has issues, but then, that's also my objection to the REx...it compromises the BEVs functionality, and the range is still not enough for me to be convenient. The Volt had some good ideas, but it was also a GM product...IMHO, they've gotten a lot better, but still have some issues.
There are not all that many CCS charging stations out there, although more are being built. Plus, few of them can charge at the current maximum rate of 350Kw at 800vdc, nor are there vehicles out there in any kind of quantity that can accept it. As a result, take something like a Tesla with a large battery, if you're not near a CCS or supercharger, and need a full 'tank' to go somewhere, you could be talking about over a day at some EVSE units as many of the public ones out there are 208vac and maybe 20-30A. That, to me, is just unrealistic. Not everyone is going to limit their travels to the interstates or other areas where the plans are to place fast charging...but, you are likely to find a gas station and the vehicle can be fully ready to go in minutes rather than hours.
This will change over time. It's sort of a chicken and egg conundrum...you need the demand to supply the charging infrastructure, but that won't be prevalent until there's enough vehicles requesting it...which one comes first, the demand or the supply...in our current environment in the USA, the government isn't promoting any new stuff. What is being built, mostly started before the current administration.
