New-model cars are loaded with more driver distractions than ever before, including navigation systems that take an average of 40 seconds to program, according to a study of more than two dozen 2017 vehicles. “It’s a staggering increase in the technology and complexity of the vehicle in the last two to three years,” said David Strayer, lead scientist in the study by the AAA Foundation for Traffic Safety. Distracted driving is underreported because many drivers don’t admit to their distraction, but in 2015, the National Highway Traffic Safety Administration recorded that 3,477 people were killed and 391,000 were injured in motor vehicle crashes involving distracted drivers. The AAA foundation tested the distraction factor in 30 different new car models, concluding that 23 of them had technology on board that demanded the driver pay a high or very high level of attention to it while the car was moving. “We’ve seen the things that are enabled in the car keep growing and growing,” Strayer said.
