Drivers are slower to respond to emergencies in semi-automated cars

Researchers found that drivers who were watching videos while the car was in autonomous mode responded more slowly and severely to an emergency. The study suggests that new ways of assessing driver safety will be needed as technology develops, including designing systems to improve driver response during system failures.
