Indeed, hydrogen fuel cells have achieved precisely what the big automakers intended. GM unveiled their “leapfrog strategy” in 2003 https://www.newyorker.com/magazine/2003/08/11/the-car-of-tom... GM even built a Disney exhibit to cover themselves in hydrogen glory while forever continuing to sell gas and diesel SUVs and pickups. I am reminded of the Cali Cartel’s big PR push about how they were abandoning cocaine as product and violence as a tool.
