The numbers from that article suggest (vaguely) that "used
correctly" means you only use 25% of the available capacity before
recharging, so that's rather a big chunk off the advertised range
of the vehicles. It probably does apply to many urban commuters,
but EVs are advertised now as being replacements for internal
combustion powered cars, so presumably many are used as such in
longer trips.

Also the article's about solar power, not electric vehicles, so
their conversion of charge cycles to years probably isn't based on
factors relevent to vehicle use.

My guess is that many won't make it to 10 years in useful
condition, but some will, which is actually the same as I've
experienced with laptops from different users. My laptop experience
also suggests that battery quality is a big factor as well (cheap
no-name replacement packs die much sooner than OEM batteries).
