> Brazil does not "fuel" cars on sugarcane any more than the US fuels its cars with corn.

In Brazil "ethanol" is sold separately from normal gasoline, and as far as I know it's entirely made from sugar cane, without fossil fuels. It's why flex cars are so popular there, since they can use either fuel depending on what's cheaper.

Meanwhile, you can't buy 100% corn-based fuel in the US.

sure, but Brazil is a net importer of refined petroleum. That exposes them to the global oil price.

Even though you cannot buy 100% ethanol in the US, the US alone is responsible for over half of global ethanol production, mostly from corn.

Regardless, any EV will almost certainly be cheaper to operate on electricity, rather than using corn, petroleum, or sugarcane for fuel.
