Smartphone Accidents

First there was the hazard of talking on the phone while driving.  I would say this may have apexed around 2002-05.  Next, there was texting while driving, say 2009-2013.  Now it seems that everyone has their head down at traffic lights.  I looked around at a traffic stop yesterday and saw three drivers surrounding me in three cars all doing the knowing tilt of the head to the lap.  There is so much to do and keep up on on the phones, it appears to be addictive and neurotic to the point of self-implosion.  Anecdotally, I would have to guess that accidents on I-40 are up 35% just in the last year based on the traffic and accidents I'm see on my weekly commute to Raleigh.
