A Good Form of "Drunk Driving"

The number of alcohol(ethanol)-driven cars increases sharply in Brazil.
Brazil produces cheap ethanol that are stopped by tariffs in the U.S. and Europe, but in Brazil ethanol sales aren't stopped by that, of course. With the sharp increase in oil prices, these cars are becoming increasingly popular. Which is good not just for Brazil but for the world as a whole given that high oil prices damages the world economy and empowers governments like Saudi Arabia and Iran.
