Head Injury? Avoid Self-Driving Cars!
21 Aug
Summary
- Concussed hockey players reacted slower to take control of self-driving vehicles.
- Athletes showed an 81% takeover success rate versus 93% for others.
- Self-driving cars need better systems for varied driver responsiveness.
Individuals with a history of head injuries are advised to exercise caution around self-driving vehicles, according to recent research. A study published in Traffic Injury Prevention found that athletes who had experienced repeated concussions were notably slower to respond when required to take manual control of a conditionally automated vehicle.
During testing in a driving simulator, hockey players with concussion histories demonstrated an 81% success rate in resuming manual driving. This contrasts with a 93% success rate observed in a control group without significant head impacts. The athletes also spent less time maintaining successful control and had greater difficulty processing information post-takeover.
Researchers emphasized that while self-driving cars can manage routine highway driving, human intervention is crucial for complex scenarios like sudden stops or pedestrian encounters. The study raises questions about drivers' ability to smoothly transition from non-driving tasks back to active control, suggesting a need for more adaptive intervention systems.
