Question: DISTRACTED DRIVING According to a study of 100 drivers in metropolitan Washington, D.C., whose cars were equipped with cameras with sensors, the distractions and the number of incidents (crashes, near crashes, and situations that require an evasive maneuver after the driver was distracted) caused by these distractions are as follows:
where A = Wireless device (cell phone, PDA)
B = Passenger
C = Something inside car
D = Vehicle E Personal hygiene
F = Eating G Something outside car
H = Talking/singing
