Automotive companies like Chevrolet and Volkswagen are hoping to clear diesel's bad name and convince American drivers that it's the new clean fuel. The owners of these trucks aren't helping that cause.
It's called rollin' coal. Diesel truck owners spend anywhere between $1,000-$5,000 to thumb their nose at fuel efficiency, sometimes literally leaving greener cars in a cloud of smog produced by one or more smokestacks, according to Vocativ. That belching black smoke that covers the road is produced by hitting an installed switch that feeds excess fuel into the engine; a practice started in the rural motorsport known as truck pulls.
These days, drivers will roll coal to pollute, harass pedestrians and punish green drivers -- or really anyone else -- for their choice of car. It may seem like good old boy fun, but it's dangerous as well as dirty. These enthusiasts will often blind cars following too close or coming from the other direction, greatly raising the risk of a crash. Talking Points Memo reached out to Liz Purchia, the press secretary for the EPA about rollin' coal.
"The short answer is this is illegal," Purchia told TPM.
