The laws do nothing, anyone who drives daily can tell you that. If you pay attention within minutes of hitting the road you'll see at least 2-3 people straight up looking at or using their phone while driving. Every. Single. Time.
I saw 2 this morning, one lady driving by the bus stop staring at her phone where I'm standing with mine and a bunch of other kids, and another not even 20 minutes later when I was driving to the bank.
This is on surface roads in neighborhoods, drive on a freeway sometime and just try to count how many people you see using a smartphone while flying along at 70 MPH in say, a 20 minute time frame. You'll lose count.
