This describes states, not any one car, and it does not show that the left measure produces the right one.
Every state with 10 or more complaints, most over-reported first: state, on-road nitrogen oxide emissions, tons per year per 1,000 residents (epa nei 2020), complaints against expected, complaints filed.
What it shows: States with more on-road nitrogen oxide emissions, tons per year per 1,000 residents (epa nei 2020) tend to sit higher on the chart across 50 states: a pattern in the data, not proof of cause.
