> EVs are still unsuitable for many purposes

One purpose where EVs are unsuitable - at least for now, and perhaps for a very long time - if off-road driving.

First off, the battery technology isn't quite there yet; everything else technology-wise works and exists, and frankly would be damn awesome in a 4wd vehicle (the torque and the ease of controlling it, for one example).

But the battery is the biggest stumbling block. For a 4wd off-road vehicle to be electric, the range would have to be able to be north of 300 miles (with all the weight and such a fully-stocked off-road vehicle needs - the frame, the tires, lift equipment, recovery gear, armor, etc - all of that before the weight of the batteries adds up to quite an amount).

For an ordinary automobile, we're pretty much there (or close enough). But the battery weighs quite a lot, and isn't nearly as energy dense as fossil fuels. For instance, on the Model 3, the battery is roughly 1/4 of the total weight of the vehicle, and gets you about 300 miles.

But for something like a Jeep Wrangler JK (which weighs approximately the same) the weight of fuel is only 1/27 of the total weight of the vehicle, though it gets you about the same range of 300 miles.

Now you might say they seem pretty similar, but that's for roughly a stock configuration. With the JK, I have about 6-7 times the "breathing room" of adding extra stuff to it (bigger tires, skid plates, recovery gear, etc) before I hit the same 1/4 of the weight level of the Model 3. While my mileage will suffer, it probably won't suffer as much as if I did the same to an electric version of the vehicle.

An electric JK has been built - conversion kits are available:

...and the vehicle performs admirably. While it has proven capable for this, there were a couple of caveats:

1. IIRC - the vehicle was trailered in and out of the area; it didn't drive there, run the trail, then drive home.

2. It had to be charged at a base camp; I am not sure what that entailed.

Those are big things - not everyone trailers their off-road vehicle; I would imagine that many drive to a trail, do the trail, then drive home. Most carry extra fuel (at least they do if they know what's good for 'em).

They don't carry that fuel in a tank on a trailer, nor do they generally set up a "fueling staging area" in order to get home or finish the trail. They carry the fuel with them.

You can't do that with an electric 4wd vehicle - at least not easily. You'd have to either (somehow) carry an extra battery pack (on a trailer or something), or you'd have to carry it with another vehicle, or stage it somehow, or something of that nature. Or you'd have to have a generator setup (and brought in the same way). Forget solar panels; you couldn't set up an array large enough to charge the vehicle in any reasonable time span.

These and other reasons (such as the cost - electric conversions are not cheap, and that's on top of an already expensive vehicle) will likely keep me out of the offering for a long while. For a certain segment of the population (those with a lot of money to play with, mainly) - they are available, although they are more a curiosity than a practical system - but that's just my opinion.

For other uses, though - in fact, most typical uses - I think electric vehicles are ready for the mass market and practical for most use cases. I'd personally love to be able to get something like a small electric pickup for a daily driver to go to work, and the occasional need I sometimes have to haul things from a home improvement store or the like. Basically, I'd love to see a return of the Ford Ranger EV they once sold, but with today's LiPo tech and not the old and heavy lead-acid they used in the past...
