Technology

You're mostly right. But I don't agree on the last part. Hydrogen production can't be done in your backyard. But electricity can (and I forgive you if have no backyard, these next few points may be less relevant if that is the case).

Unlike hydrogen, electricity production is affordable, scalable, and ubiquitous. And that small detail changes the benefits dramatically.

• The idea of being your own gas station, from the grid, or from your own solar, is really compelling. No one likes being at the mercy of fluctuating energy prices, or, as in this case, unreliable and scarce availability of fuel.
• Many people don't like going to gas stations (e.g. women and personal safety). Totally doable outside of road trips.
• If you are generating your own electricity you will need batteries anyway. Might as well put wheels on them: two birds one stone.
• Even if you don't generate your own power, you still want power security during outage. Since the battery is on wheels, you can drive it to a place that does have power to top up.

Again, I can see that these are less compelling points if you live in a super dense area and utilities and supply chain there are really dependable. But this is hardly the case everywhere.

And then there's the build of the car itself. Honestly, I know nothing about it, but something tells me the simplicity of battery and electric motors makes those cars more practical to build, especially if the battery itself is commoditized as part of a complete electric grid solution.
