So not only are they diluting gasoline with less energy dense substitutes (ethanol) they are using perfectly good food to do it.

By lowering the energy density of fuel, you need to burn more of it. Number 1, more litres purchased means more carbon tax. Number 2, manufacturers need to compensate by making even more fuel efficient vehicles by running the engines in more extreme conditions (driving up nitrous oxides, which is the root cause of Volkswagen’s cheating) or switching to more exotic alloys to reduce vehicle weight. More exotic alloys need minerals from mines from places where they don’t give a shit about emissions, and then ship them half way around the world to be made into car parts.

It is far more environmentally responsible of me to continue driving my 15 year old truck then it is to buy something new that has pieces from all over the world and has all that hidden emissions from the manufacturing.
