(AAA news release) According to a story posted to the AAA Newsroom on Wednesday, hands-free technologies might make it easier for motorists to text, talk on the phone, or even use Facebook while they drive, but new findings from the AAA Foundation for Traffic Safety show dangerous mental distractions exist even when drivers keep their hands on the wheel and their eyes on the road.
According to the story posted to the AAA Newsroom:
The research found that as mental workload and distractions increase reaction time slows, brain function is compromised, drivers scan the road less and miss visual cues, potentially resulting in drivers not seeing items right in front of them including stop signs and pedestrians.
This is the most comprehensive study of its kind to look at the mental distraction of drivers and arms AAA with evidence to appeal to the public to not use these voice-to-text features while their vehicle is in motion.
“There is a looming public safety crisis ahead with the future proliferation of these in-vehicle technologies,” said AAA President and CEO Robert L. Darbelnet. “It’s time to consider limiting new and potentially dangerous mental distractions built into cars, particularly with the common public misperception that hands-free means risk-free.”

Cognitive distraction expert Dr. David Strayer and his research team at the University of Utah measured brainwaves, eye movement and other metrics to assess what happens to drivers’ mental workload when they attempt to do multiple things at once, building upon decades of research in the aerospace and automotive industries.
Using established research protocols borrowed from aviation psychology and a variety of performance metrics, drivers engaged in common tasks, from listening to an audio book or talking on the phone to listening and responding to voice-activated emails while behind the wheel.
Researchers used the results to rate the levels of mental distraction drivers experienced while performing each of the tasks. Similar to the Saffir-Simpson scale used for hurricanes, the levels of mental distraction are represented on a scale:
Tasks such as listening to the radio ranked as a category “1” level of distraction or a minimal risk.
Talking on a cell-phone, both handheld and hands-free, resulted in a “2” or a moderate risk.
Listening and responding to in-vehicle, voice-activated email features increased mental workload and distraction levels of the drivers to a “3” rating or one of extensive risk.
“These findings reinforce previous research that hands-free is not risk-free,” said AAA Foundation President and CEO Peter Kissinger. “Increased mental workload and cognitive distractions can lead to a type of tunnel vision or inattention blindness where motorists don’t see potential hazards right in front of them.”
