Brazil has been building cars which can run on 100% ethanol since the 1970s.

These are not obscure facts; this is common knowledge the US teaches to schoolchildren.

In the US gasoline is a 10% ethanol blend, sometimes 15%. E85 is available only in some midwestern states (I've NEVER seen it for sale anywhere on the west coast) and it's only good for flex-fuel vehicles, which most manufacturers stopped building ~ 10 years ago when the free money from the government shifted towards EV incentives.
