Awhile back when no texting laws were just starting out I remember thinking it was so stupid because my state (Michigan) already had a no distracted driving law.

I don't see how it's any different than eating, smoking, reading, or whatever else people do in their car that makes it harder to drive.

unfortunately the law has to balance principle with practicality. it's hard to imagine a way of detecting a wide range of distracting behaviors without some sort of pervasive surveillance. would you be willing to accept a camera in your car than an LEO can tap into at any time?
