Had to drive the last couple weeks to work after bike commuting for a decade. The level of selfish, self-absorbed, and dangerous driving due to cell-phones blows me away. Driver after driver thinks nothing of staring at a screen oblivious to the light turning green and a line of cars behind them. Of changing lanes staring at a screen without signaling. Of talking on a phone and driving 10 mph below the speed limit. I've seen this behavior about 5 times on average each direction, each day.
