Why this case is “alleged”

No court, coroner or official investigation has yet found that Tesla Autopilot (Autosteer + Traffic-Aware Cruise Control), Model S caused or contributed to these deaths. The case is listed because it meets our standard for a credible allegation. It will move to the confirmed count only if an official body makes such a finding.

Legal status

The Tesla driver, Kevin George Aziz Riad, pleaded no contest to two counts of vehicular manslaughter and was sentenced to probation (2023), the first US felony prosecution of a driver using a partial-automation system. The families' civil suits against Tesla (Los Angeles County) were settled on confidential terms in 2025.

Notes

The driver's conviction concerns his own conduct and makes no finding about Autopilot, so it doesn't make this case confirmed.
