Crash Calculator
Compare AV crash rates from SGO data with human driver crash rates. Enter miles driven to see relative risk.
US average is ~13,500 miles/year
Human Crash Rate
2.3
per million VMT (police-reported)
≈ 0.0310 crashes/year at 13,500 mi
AV Incident Rate (SGO)
21.5
per million VMT (estimated)
≈ 0.2903 incidents/year at 13,500 mi
Relative Risk (AV vs Human)
9.3×
AV incident rate is higher (but SGO reporting thresholds differ from police reports)
⚠️ Important caveats: These rates are not directly comparable. SGO reports have different reporting criteria than police crash reports. AV mileage estimates are approximate. Human crash data includes all vehicle types. This calculator is for educational purposes only.
