But as far as “cost of production” goes, gotta think the savings in not having to redesign the automobile drivetrain would save a lot of cost?
Automakers redesign their drivetrain constantly. The real savings would come from smaller, less complex drivetrains.
For us, the savings would come from them being lighter, more energy dense, and fewer moving parts.

Losing the need for a transmission is one huge gain in my personal EV experience.

In 40 years of driving, I’ve replaced 2 transmissions. Not an issue for me.

I was talking about the Delete of that energy wasting device not required by electric autos. :)

There is still a gear reduction box, but it doesn’t waste near the power that a transmission does.

Electric vehicle’s entire drivetrain:

And here’s the fuel tank:

Yeah the loss of most fluids, if not all fluids, will be a huge relief. No more oil changes, transmission fluid changes, filters, etc. Those items in a larger truck are surprisingly expensive now.

Just an oil change on my truck now runs me $35 when I do it myself. As I get older, I don’t think I’ll miss doing it very much.

The big, big advantages hydrogen has are no air pollution and no dead batteries that are not easily recycled (junked?). So what is the "true cost" factoring in the myriad of associated costs with those?
Myopic vision. You are pretending the fuel cell never wears out. The fuel cell contains more exotic materials than lithium batteries and is very sensitive to the purity of the hydrogen and cleanliness of the air used to react with the hydrogen.

A kWh of electricity used to produce hydrogen will move an EV twice as far if one skips the hydrogen step. H2 currently costs 5x its equivalent in gasoline.

..... ^^^ for fuel cells with current technology .....

What were the prospects of an EV 20 years ago before money was sunk into research?
