Another good point that gets overlooked. Not only
disposable batteries. I saw a claim recently that electric
could be even more dirty due to getting the power from
coal-fired power plants. I didn't read the details, so I'm
not clear on whether that's a credible claim. But it's a
worthwhile point, either way. Electric is assumed in
popular thinking to be inherently better.
With ICE vehicles you're guaranteed to be using fossil fuels. However, with
electric vehicles the energy generation is a mix and can evolve to include
more sustainable sources.

Not quite guaranteed. There is always hydrogen.
Hydrogen cars are not ICE.
2H + O = H2O = combustion.
Need to work on your chemistry. It's

2H2 + O2 - 2H2O + heat

It was not meant to be a chemical equation. I was pointig out that
hydrogen powered engines are internal combustion engines.

I showed you two methods in a previous post.

This one, is the fuel cell summary. The equations
involve electrons, and the electrons are harnessed
to do work.

Anode Reaction: 2H2 + 2O2− → 2H2O + 4e−
Cathode Reaction: O2 + 4e− → 2O2−
Overall Cell Reaction: 2H2 + O2 → 2H2O

For regular combustion, the ingredients are diatomic molecules.
The output here is heat (exothermic), and steam pressure
might move the wheels. (As doing other things with the
heat, might waste more of the output.)

2H2 + O2 → 2H2O

I was hoping to show a picture of a fuel cell bus
with a cloud of steam behind it, but I was unable
to find the video. I can find web pages which describe
heat coming from fuel cells, but then again, they
mention high temperature fuel cells which rely on
being hot in the first place. Googling an answer
has been a waste of time, to get that kind of detail.
