This is the second time in a few weeks that I've nearly been crushed in a head-on collision by a car driving down my quiet, leafy street that inexplicably began to veer into my lane. I'm driving 30 mph. He/she's driving 30 mph. Except for my reflex to swerve into the curb, honk and pray, I wouldn't be writing these words. What could explain such stupid driving behavior? In both cases, they were looking at their cellphones while the car drifted off into opposing traffic. Readers, help me out here: how can we stop this epidemic of texting, emailing, message-checking and surfing the web - while driving?
