One thing that is unclear is that the two independent images, one showing an individual using a phone where they may be personally identifiable and a second showing the car's license plate. So they fine the registered owner of the car for the driver being distracted? What if I'm in a car share? Do they subpoena the companies records or just fine them and have it passed on a la rental cars and speeding tickets?

I think distracted driving is a real problem but just like photo radar this punishment weeks after the fact when you get a fine in the mail will have very little impact on the underlying behavior. It's like watching your kids do something unacceptable and then grounding them a week a later as punishment. If they wanted to really change behavior they need to get in the faces of drivers like drinking and driving check-stops; pull them over, ask them if their using their phones, warn them of the danger (they could check for impaired driving at the same time). The problem is cops on the ground costs money; this makes money.
