You can hit the open road and just keep driving - as long as a complex global energy distribution network keeps up just-in-time fulfillment of fuel to gas stations along the way.
Whereas an electric car, powered with charge gathered from the sunlight that struck the roof of your own home? That’s truly independent.
You can get a car, that you can charge at home, for free, AND you can also use it to run your house if the grid goes tits up again? Sold!
Pretty damn exciting.
Yeaaaah, I kinda think smartphones were bigger change than this. It's nice, but not a flying or self driving. Just different, cheaper source of energy. It does not enable anything new, other than charge.
Think of someone in a village in Africa.
But what never gets dull is laughing at people paying to fill their cars with liquid explosives.
