You are wrong and right.

Wrong because Brazil DOES fuel cars on sugarcane alcohol. Most petrol stations in the country have pumps for sugarcane alcohol, nearly all the ICE cars sold in the last two decades have a flex engine (in the past you had to chose when buying the car if you wanted a alcohol engine or a gasoline engine, now the engines just takes whichever you trow at it and adjusts the injection accordingly), and roughly half the personal vehicles in the country run daily on alcohol. That fact has softened this oil crisis a tiny tiny bit in the country (when oil is expensive many people just pump alcohol instead of gasoline).

And right that electricity is much cheaper than gasoline or alcohol, so people are changing to EVs because of the cost savings in fuel. In fact electricity was already much cheaper even when the price of oil was down, what was holding back EV adoption in the country was never the price of oil, but the relatively high purchase prices of EV vehicles (the average upper-middle-class Brazilian can't afford a Tesla like an American or European can), but the latest batch of basic EVs (like the BYD Dolphin-mini/Seagul) started to break that barrier about one or two years ago, and are now on the top sales charts.
