Synthetic fuels (including hydrogen) do still make a lot of sense for heavy stuff like trucks, buses or trains, and aircraft where the energy density is a big plus. Those are where you'd expect to see hydrogen take off first, not passenger cars. Same as how diesel started in trucks - expensive engines but economical when amortized and worth it for heavy usage applications.
If they couldn't crack those areas, no chance in the highly competitive passenger car space.
Trucks and busses would be better off with battery swaps at depo like electric forklifts do. More mileage more towing weight for trucks, just stack more batteries. Overweight? Use a diesel.
Trains is an easy one, over head lines.
Aircraft, I think short distance trips <1hr maybe otherwise biofuel. Likely we’ll see biofuels widely used by 2040. Electric motors on a 777, I’m not sure.
