Do you use your phone while you drive?

I passed a potatoe chip dellivery truck on a busy street as he was texting while driving 40mph. He was intent on watching his screen as he plugged away at the keyboard, only watching the traffic over his knee, which held the steering wheel while his hands were busy operating the phone. All this could be seen as he was driving with his door open. YEAH, THERE OUGHTTA BE A LAW…
