Privacy, as you might guess, is a concern. The Cellebrite-made technology involved in the law can't access the actual contents of your phone -- it can only tell whether or not you've been busy. Cops would still need a warrant to see if there really was an on-the-road conversation, in other words.

If the bill becomes law, it could serve as a better deterrent to the crowd that ignores distracted driving laws. However, it does raise some questions. How accurate is the technology, for example? Will it mistake background phone activity (such as notifications or uploads) for active use? What happens if you dispute the allegations -- will you have to consent to a detailed phone search? As good as the measure might be, it could lead to wrongful convictions if the technology is either imperfect or misused.
