Up to 27 seconds of residual distraction trails use of digital assistant software and infotainment systems in automobiles, the University of Utah reported Thursday. The report, done for the AAA Foundation for Traffic Safety, follows a similar set of studies conducted last year that concluded that infotainment systems distract drivers when they’re using them on the road. This time, researchers looked at the aftereffects of driving while using infotainment systems, the ones native to automobile, and digital assistant apps on mobile devices.
