Came here to make sure this point was made. The increased death of bicyclists, pedestrians is a pretty easy thing to measure. There are other things that are overlooked or at least not mentioned due to smartphone users driving-

1) increased commute times because distracted drivers don’t follow the flow of traffic well 2) increased likelihood of collisions as traffic starts and stops on highways. I’m certain I see more rear end collisions on the freeway in the last 10 years than the prior 10. 3) Lost productivity at work.
