Efforts to ban drivers from holding a phone or other device in their hand while driving died yet again in the General Assembly this year, despite an successful effort to address some legislators’ concerns that similar bills in the past could open to the door to lots of “driving while black” traffic stops. It’s not completely clear whether opposition arises from a view that Virginia shouldn’t enact “nanny state” laws or whether legislators perhaps are worried that a dip in cell phone usage minutes might hurt telecom companies’ or hospital revenues.
