Someone put some street art up at intersections locally of a silhouetted pedestrian with their neck craned at their phone, incidentally right where your eyes would be when you are looking at your phone just like the silhouette and crossing the street. I'd like to think that this artist has saved more pedestrian lives than the local department of transportation at this point.
Not unless someone has found a way to make crossing the street as stimulating as watching cute kitten videos. I really think it's almost a neurological type of issue-- phones are just so stimulating there isn't much in the real world that can compete. Even when driving a car people will glance at their phones for dangerously long. They know it's dangerous, but they're not necessarily making the conscious decision to take the risk-- they just take a quick impulsive glance to see what that person is texting them
Smartphones have been a boon for chiropractors, though.
