Over half of US drivers report they eat or drink (73%), adjust controls in their cars (67%), talk on the phone (57%), or use their GPS (55%) while driving. As might be expected, the percent of drivers engaging in an activity is inversely proportionate to those who perceive it as being dangerous although there are a few exceptions.
Using a GPS, however, is perceived by 86% of US drivers as being dangerous — but 55% do engage in this activity while driving.
Across all drivers, the highest incidence of reported accidents or near misses happen because of daydreaming and texting (despite the low incidence of drivers claiming to engage in these). Searching for personal items and dealing with children/pets result in the next highest incidence of accidents/near misses.
