IMO your post clearly demonstrates that you have little knowledge regarding hydrogen.

"Hydrogen also creates emissions to produce."

So you are unaware of the Hazer process or solar powered electrolysis ? The Hazer process is actually carbon negative if Biogas is used as the feedstock.

"So maintenance and repair times, outside emissions, cost will play into end user decisions."

The only emission from a hydrogen powered fuel cell is water.

"Also hydrogen is an engine bolted into an engine bay, versus electric motors in the wheel on EV."

Engine ? Lol ! Hydrogen cars are EV's which use hydrogen and a fuel cell to generate the electricity.
