text: The reason that its a bad idea to be on your phone during driving is that it takes away your attention from the road. Driving is already a multitasking operation. We have to balance our speed, gas level, directions, music, air conditioning, and other drivers. The last thing we need is another thing to focus on, especially an entertainment device that we already struggle to put down. All cell phones do for drivers is add another thing to focus on, and the list of things for drivers to focus on is already too long.
