"Hang up and drive"

An interesting study about what we all observe (that is, unless we're continually distracted from such observations because we're talking on a mobile phone) while driving: talking on a cell phone while driving affects our driving. It doesn't matter that it is hands free. From my time as a prosecutor, I learned that we test for impairment by giving suspects "divided attention tasks" because driving epitomizes multi-tasking and "substances" impair our ability to do it. Involvement in highly-engaging conversation compounds the challenge of driving/reacting-while-driving.

Now; if I could only discipline myself not to use my mobile phone while driving, I could get a "hang up and drive" bumper sticker.
