The problem arises because US ethanol is derived from corn. Elsewhere
it is derived from sugar cane. It also cause increased emissions of
formaldehyde and ozone. Both cause smog and cancer.
Adding ethanol is another way of improving the "anti-knock"
properteries rather than using lead.

You're as dumb about chemistry as you are about politics, Harry.
Ethanol "marginally" increases octane of fuel, as the AKI of neet
ethanol is somewhere around 115. So E10 would have an octane rating a
couple of a points higher than plain gasoline. Start with 87 octane -
28 points spread between the gasoline and ethanol. Add 1/10 ethanol
and you get 2.8 points - but the ethanol is not anhydrous - it
contains water - which lowers the concentration - and therefore the
octane increase.
I know it's not 100% linear - but that is the rough essence of it.
