Many of the interactive information and entertainment systems turning up in newer cars may be distracting enough to increase the risk for accidents, especially for older drivers, according to Reuters Health citing a new AAA Foundation study.
The systems often require drivers to take their eyes off the road for extended periods for when performing simple tasks such as navigation or radio tuning. And researchers found that the problem is worse for seniors, who looked away from the road for up to eight and a half seconds longer than younger drivers.
“We know from prior work that younger drivers are struggling,” said study coauthor David Strayer, a professor and director of the Center for the Prevention of Distracted Driving at the University of Utah in Salt Lake City. “We found that older drivers take their eyes off the road for longer when they are trying to interact with this technology.”
The new findings are particularly important given that there will be increasing numbers of senior drivers on the roads, said Jake Nelson, AAA director of traffic safety research and advocacy. And keep in mind, Nelson said, “whether it’s easier-to-see signals or striping on the roads, if it’s good for seniors, it’s good for all of us.”
For the new study, done as a partnership between the AAA Foundation for Traffic Safety and the University of Utah, researchers tested the visual and cognitive demands of infotainment systems in six 2018 vehicles.
Two groups of participants - between ages 21 and 36 and between 55 and 75 - were asked to use the interactive vehicle technologies to make a call, send a text message, tune the radio and run a navigation program. To do that, they needed to use voice commands as well as touch screens. Some of the more complicated systems used multiple menus and cumbersome voice command functions that made it hard to complete tasks while watching the road.
Strayer and colleagues compared the amount of time it took younger and older participants to complete a series of tasks and found: calling and dialing took younger people an average of 17.7 seconds as compared to 22.4 in the older group; text messaging took younger people 27.7 seconds to complete versus 33.8 seconds in the seniors; and navigation entry took the younger adults 31.4 seconds, versus 40 seconds in the older group.
Strayer suggests that consumers put at least as much energy into checking out a car’s infotainment system as they would in buying a new phone. “You need to be a smart consumer,” he said. “Make sure you don’t buy a car you can’t use.”
Beyond that, he said, “if your car has features you need to figure out, figure out how to use them before you start to drive.”
