Every step of energy conversion would result in a net loss. Fuel to motion, motion to generate electricity, charge/maintain batteries, converted back to electricity and finally back to motion.

It would be more efficient to just drive on gasoline.

It would be more competitive if they could make the batteries easily swapped. Charging stations could swap or charge depending on time constraints.

Sure, you make a point. Perhaps not enough to negate the idea. I like your idea of swapping the batteries.

When you buy a new gas grill, do you swap the tank for an old, rusty one at a swap a tank place, or do you keep your new tank and just fill it up?

Connector failure and battery condition are issues that can be handled. My phone can tell me the condition of its battery. A car could do the same. There are high amperage connectors that can handle thousands of connect cycles. Forklifts have been doing so for years.

Coming from under the car seems inefficient although thats the best place for weight

Diesel generators are much more efficient than diesel or petrol powered vehicle motors. Constant RPM increases efficiency.

IF you want to see something weird go to youtube and find a video on the Pontiac G8 engineering mode. Once you get into that the screen in front of you tells you everything going on with the car. It can even give you the part number of a component that is not within spec, allowing you to replace it before it fails.

IT can also tell you the condition of the battery so you can replace it when it is at about 20%.

And that is from 2008. I wonder what they could do today if they wanted to?

Maybe you don't even own the tank. Just pay to trade for one that is equal.

Slide it out the back. Its under the center hump.

Sort of like a small propane tank. Suxs if you trade in a new one for a scraggly one. Maybe worse for batteries.

Hard to make electric motors sound sexy. I kind of smiled to myself when I saw one maybe a year ago that was badged “Dual Motor.”

However, they are still quite expensive. And the charging times aren't attractive at all. I'm still a proponent of Hydrogen fuel cell vehicles, especially to bridge the gap in the market. They can be filled much like ICE vehicles and still have the benefits of being a net zero emission vehicle.

I hope we get both options, both electric and HFC, with both taking up portions of the market.

With hydrogen, it’s as dirty as whatever power was used to make the hydrogen. I haven’t read up on it lately but I gather one of the most economical ways is to pull it out of natural gas. Seems a bit odd. What do you do with the carbon that’s left over, and it’s hard to imagine that it’s a flawless process. Cracking it from water with electricity would be the ideal way I guess. Coal fired electricity often as not.

Ah, search indicates that 95% of hydrogen comes from natural gas at present.

Look into solar dissociation. reflected, not 'electric panels'. zero carbon there.

Look at Iceland. They use the Volcanic activity to produce Hydrogen. So, technically "Free' Energy. Also, since a small land mass, transport wouldn't be as big of a problem.
Yellowstone sits on a mega volcano. Don't know when its going to blow. Yeh, cue Jimmy Buffet.

And why is that not the most commonly used method?

The thing I like about hydrogen is that it fits our current way of fueling a vehicle. The next great thing about it is that it can be generated anywhere and by a number of means.

Yes, we can get it from electrolysis, natural gas, etc. But that means that wherever we need it, we can use a process that is best to produce it locally. We don't need to truck it all over the place (although we could).
