AT&T commissioned Braun Research poll finds nearly 1 out of every 3 people use Facebook while driving. Driving their automobile. On the road, in the United States, where you live. The study was done by poll, asking 2,067 in the United States aged between 16-65 who use their smartphone at least once a day AND drive at least once a day a number of questions. What was found was a bit shocking, to say the least. Not only do a lot of people drive while using their phone, a lot of those people do some pretty involved things on their phone whilst driving.
