Casual observance from one who used to do a lot of “work sampling” studies and also “watches” the dynamics of human movement….spent a LOT of time sitting in airports…
I have come to the conclusion that part of the Triangle’s traffic mess IS cell phones. People using stop lights to “catch up” on email, texts, phone calls, play games, etc.
If you watch the progression of folks pulling away from a stop light, I have seen FASTER responses in the Independent Care living center where my mom resided by the little old folks in their “electric” chairs.
Their reflexes were faster….but they did not have their electronic toy embedded in their paws..
Phones have added at least 25% to the commute time around here….as well as other places….
