Built-in vehicle infotainment systems are more distracting to drivers than Apple CarPlay and Google's Android Auto, according to new research from the AAA Foundation for Traffic Safety.
The study could have implications for future automotive technology development.
The study examined five 2017 and 2018 vehicles to determine how much visual and mental demand was placed on drivers for tasks including: selecting or programming audio entertainment, calling and dialing, text messaging and programming navigation. The vehicles selected -- the 2017 Honda Ridgeline RTL-E, 2017 Ford Mustang GT, 2018 Chevrolet Silverado LT, 2018 Kia Optima and 2018 Ram 1500 Laramie -- were chosen based on whether the built-in system supported CarPlay and Android Auto.
In the study, the Kia Optima, Chevrolet Silverado and Ram 1500 generated overall moderate demand, while the Honda Ridgeline and Ford Mustang generated very high demand.
Also examined: Demand associated with completing tasks based on using voice commands, touch screens or other interactive technologies, and how the demand varies across vehicles and systems. These controls can contribute to distracted driving, which -- according to the National Highway Traffic Safety Administration -- results in more than 390,000 injuries and 3,500 deaths per year.
The AAA study found that "CarPlay and Android Auto systems generated an overall moderate level of demand, whereas the built-in (native) systems led to overall very high levels of demand."
The study also noted:
CarPlay and Android Auto were 5 seconds faster on average than the vehicle's native system when making a call and 15 seconds faster when programming navigation, the research found, timing that could significantly reduce the time drivers spend looking away from the road and steering wheel.
"Google and Apple are proving that it is possible to reduce the level of demand in-vehicle infotainment technology places on drivers," David Yang, executive director of the AAA Foundation for Traffic Safety, said in the AAA release. "While improvements are necessary before any of the systems can be considered safe to use while driving, this research shows that smartphone-based software has the potential to offer a simpler, more familiar design that is less confusing to drivers, and therefore less demanding."
