TSLA Fear & Greed Index
Loading the latest data
How Tesla’s cars score in US crash tests, what Tesla’s own collision data says about driving on FSD (Supervised), and which federal safety investigations are open.
Two US programs test how well cars protect the people inside. NHTSA, the federal safety regulator, awards up to five stars. IIHS, a research group funded by insurers, rates each test Good, Acceptable, Marginal or Poor and gives Top Safety Pick awards to the best performers.
NHTSA estimates the chance of rolling over from a vehicle’s stability and a swerving test. Under 10% earns five stars; 10% to 20% earns four.
Tesla reports how many miles its cars travel between collisions on FSD (Supervised), compared with Teslas driven manually and with its own estimate for the average US vehicle. A major collision is one that sets off an airbag or another one-time restraint. The figures cover North America over a rolling 12 months; more miles is better.
FSD’s miles per collision divided by manual driving’s, Teslas with active safety features
Share of miles driven on highways
| Update | FSD (Supervised) | Manual, active safety | FSD ÷ manual | Manual, no active safety | US average (Tesla estimate) |
|---|
The figures come from Tesla’s vehicle telemetry and are not independently audited. NHTSA is separately reviewing whether Tesla filed crash reports on time (see below).
A collision counts as FSD if the system was on at any point in the five seconds before impact. NHTSA’s crash reporting order uses 30 seconds. Tesla does not assign fault. tesla.com
Drivers choose when to switch FSD on, and FSD miles lean toward highways, where collisions are rarer for every kind of driving.
Tesla estimates it from federal mileage data and NHTSA’s sample of crashes in which a car was towed, a different measure from airbag deployments in Teslas. Tesla calls the comparison with its own manually driven cars the most direct one. In June 2026 Senators Markey and Blumenthal, citing a Reuters analysis, asked NHTSA to review Tesla’s FSD safety claims. thestar.com.my
Cases at NHTSA’s Office of Defects Investigation that involve FSD or Tesla’s crash reporting. An investigation moves from a preliminary evaluation to an engineering analysis, which NHTSA must finish before it can seek a recall.
