Some people are capable of being fighter pilots, requiring incredible multi-tasking of reading and sorting through displayed information (albeit in a Heads Up Display), filtering out all but the important items while simultaneously steering a multi-ton piece of steel in three dimensions while also simultaneously avoiding other aircraft.

Other people can't walk and chew gum at the same time.

Laws are often written with the "lowest common denominator" in mind.
... and that's OK.

However, there are already laws against reckless (and even, in many places, "distracted") driving. The only issue I have with outlawing texting while driving is that it gives the false impression that grooming, reading, eating, etc. are somehow OK.

Somehow, it's OK to ban something technological where something mundane is just as likely to cause an accident.

My $0.02: Let the police issue citations for anyone who exhibits dangerous behavior like shifting lanes without signaling, turning in front of traffic, rapid speed changes, and so forth, regardless of whether it's because the idiot behind the wheel is texting, farding (putting on makeup), or searching for that french fry that fell into his/her lap.
