Small point about "life expectancy": It is a statistic that sounds
reasonable, but it's probably a lot more difficult to calculate than it at
first seems and can be misleading. For simplified example, suppose you have
10 dogs all born in the same litter. 5 of them die at 10 years old and the
other 5 are still living. What is the "life expectancy? Is it 10 years?
It's unknown, because the sample isn't finished yet. Since the "sample" is a
moving target and people are constantly being born and dying, the only true way
to say something like "If you were born in the year 1905, you had a life
expectancy of 81.5 years or 77.5 years or whatever. For related reasons,
it's also misleading to just look at all the people who died in a given year
and averagetheir ages at death. Population bubbles influence that.
My stupid pedantic point is you are always playing "catch-up" and it would be
more accurate to say the life expectancy "WAS" rather than the life expectancy
IS. That would be a better way of saying it rather than some nebulous
prediction of the future.
Maybe a more accurate conclusion might be the French "were" healthier despite
what they did in the past, but that sounds a little confusing...
Anyway, just my 2 cents...I'll shut up now.

And the EU OTR e-trucks already have pretty large batteries. It appears
that around 700 to 750 kWh is common, and one proposal to put an extra
battery under the trailer would push capacity over 1 mWh.

I have some doubts too.
I don't guess that it's a primary factor, but you have to think that such
improved working conditions play some small part in Europeans living longer.
For many reasons, US life expectancy is only 77.5 years, vs 81.5 years for
the EU.
The French live even longer, 83.5 years. That's despite a rich high-fat
diet, a greater smoking rate, and more Diesel vehicles producing PM 2.5.
That last factor is finally starting to change, though, as EVs become more
popular. I've read that they've mainly grabbed market share from Diesels,
and less so from gasoline fueled vehicles.

The meaning of something is established by the degree to which it
connects to other familiar things. A search engine, mapping those
connections, isn't just a model of how we think; increasingly, it
IS how we think. In time it will control meaning, the way a
traffic map controls traffic.
