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, gallons of motor gasoline burned per resident per year (seds, transportation), complaints against expected, complaints filed.
What it shows: States with more gallons of motor gasoline burned per resident per year (seds, transportation) tend to sit higher on the chart across 41 states: a pattern in the data, not proof of cause.
