How often do you pull near another vehicle and take a quick look over? These days, you will often see a driver looking at their phone. Recognizing phone use while driving is relatively easy to spot: the driver’s head is tilted down, not looking at the road. There is a particular posture, as illustrated in the photo below:

This can occur while accelerating in leaving an intersection or driving at high speed down the highway. Many drivers appear unable to keep their eyes off their phone while their vehicle is in motion.
Perhaps this is just a sign of our era? Americans love driving and love smartphones. Even as deaths while driving increase, phone use continues. The acknowledgment of a public problem with phone use while driving from years ago seems to have faded away a bit.
From a driving norms perspective, is there a polite way to signal to another driver that you can see their phone use and request they pay attention to their safety and your safety?
From a social perspective, is the smartphone the new car in that we are willing to reorganize society around using smartphone use rather than fitting smartphones into our existing social order?
