Who's in the lead doesn't
Who's in the lead doesn't matter, Bob. Gasoline was a nobody when it came out of nowhere and ousted steam, electric and diesel to dominate.
I consider 300,000 miles ONE car. I got 289k out of my first car (would have gotten more if I'd taken care of it), 320k out of another, and have two vehicles in our driveay now that I consider only 1/2 way done and just getting started at 187k and 53k.
I like electrics, but I see many problems with them as well. Did you include the massive infrastructure improvements needed to charge all those cars if even half our nation's automobiles go electric? What about all the costs to "go green" with all that production? 1/3 of our power is currently coal produced. How about all those charging stations so that someone could, conceivably, go just about anywhere and find a fast charger to keep them going?
Most hydrogen is not produced from electricity and likely never will be. There are plenty of alternatives to making it without electrolysis and plenty of ways to easily transport it or make it right at home or at the filling station. In the end, it looks to me like hydrogen is as ready infrastructure-wise as is electricity. Many of the things needed for it are already there thanks to methane.
Again, I see a future where there isn't a "winner" in propulsion systems, as you seem to want. Instead, there is a mix of options and solutions.
