A safety driver who was riding in an autonomous Uber vehicle in Tempe, AZ, during its fatal 2018 crash has been charged with negligent homicide
Investigators said the woman had been watching a video on her phone when the vehicle killed a pedestrian in Arizona.
Context & Ripple Effects
This charge closes the circle on the most scrutinized automated-driving incident on record. The [[a:929938|NTSB's 2018 report found the Uber vehicle never identified the pedestrian or braked until too late]], while Tempe police video showed the safety driver glancing away in the final seconds and investigators later said she had been streaming a Hulu show behind the wheel.
Prosecutors answering that ambiguity chose to charge the human, not the company — a negligent homicide count against the driver for a crash the system also failed to prevent. The case has since become the template for automated-vehicle liability: she ultimately pleaded guilty to endangerment in the first automated-driving fatality prosecution.
First-order effects
- The safety driver now carries personal criminal exposure for a crash that occurred in a vehicle Uber owned, programmed, and deployed — the charge treats her inattentiveness, not the system's failure to classify the pedestrian, as the prosecutable act.
Second-order effects
- For every AV operator running human safety drivers, the case makes clear that the monitoring role carries individual legal risk, forcing companies to reconsider supervision, shift lengths, and how much of the driving task they leave to an attendant expected to catch software errors.
Third-order effects
- The case sets the attribution pattern for shared-control crashes: absent explicit rules, prosecutors assign fault to the human fallback while the NTSB documents machine failures — a gap that pushes regulators toward formal standards for when an automated system, not its attendant, bears responsibility.
The trend: Criminal and regulatory frameworks are being forced to define where responsibility sits when a partially automated system and its human attendant jointly fail.
