Rankings

Manufacturer rankings based on NHTSA SGO incident data.

🔍

Key Insights

  • Tesla, Inc. dominates with 50.1% of all 7,082 reported incidents.
  • 71 total fatalities across all manufacturers.
  • Nissan North America, Inc. has the highest fatality rate at 5.3% (among manufacturers with 10+ incidents).
  • 21 manufacturers with 10+ incidents have zero fatalities.

📋 How Rankings Are Calculated

Our rankings use data from NHTSA's Standing General Order mandatory crash reporting program. Every manufacturer operating vehicles with ADS or Level 2 ADAS must report qualifying crashes. Rankings are based on the following metrics:

  • Most Incidents: Total unique crashes reported to NHTSA, deduplicated by Report ID. Higher counts may reflect larger fleets, not necessarily worse safety.
  • Highest Fatality Rate: Percentage of incidents resulting in one or more deaths. Filtered to manufacturers with 10+ incidents to avoid misleading small-sample statistics.
  • Most ADS Incidents: Crashes involving fully autonomous vehicles (Level 3-5). All ADS crashes must be reported, regardless of severity.
  • Most ADAS Incidents: Crashes involving driver-assist systems (Level 2). Only serious crashes meeting SGO thresholds are reported.
  • Fewest Incidents (≥10 reports): Manufacturers with the cleanest records among those with meaningful data.

⚠️ Important Caveats

Rankings ≠ Safety rankings. Raw incident counts do not account for fleet size, miles driven, or reporting thresholds. A manufacturer with millions of vehicles will naturally have more reports than one with hundreds.

ADS and ADAS are not directly comparable. ADS operators report every crash (even minor ones). ADAS manufacturers only report serious crashes. This makes ADS counts appear disproportionately high.

Frequently Asked Questions

How are manufacturer rankings calculated?

Rankings are based on total NHTSA SGO incident count by default. We rank by raw count because it's the most transparent metric available. However, raw rankings should not be interpreted as safety rankings — a manufacturer with more vehicles on the road will naturally report more incidents.

Why does Tesla rank first in incidents?

Tesla has the largest consumer fleet of ADAS-equipped vehicles — millions of cars with Autopilot or FSD. More vehicles means more reported incidents. However, Tesla also has the highest absolute fatality count, which raises genuine safety concerns beyond fleet size.

What does fatality rate mean?

Fatality rate is the percentage of a manufacturer's reported incidents that resulted in one or more deaths. A high fatality rate may indicate more severe crashes, but it's also affected by reporting thresholds — ADS operators report minor bumps that lower their fatality rate.

Why do some rankings require 10+ incidents?

We apply a minimum threshold of 10 incidents for certain rankings (like fatality rate and fewest incidents) to avoid misleading statistics from manufacturers with very few reports. A single fatal incident out of 2 total would show a 50% fatality rate, which isn't meaningful.

Can I compare ADS and ADAS manufacturers directly?

Direct comparison is problematic because ADS operators must report all crashes (even minor ones) while ADAS manufacturers only report serious crashes. This means ADS manufacturers appear to have more incidents per vehicle, but many of those are low-severity. We separate ADS and ADAS rankings to address this.
