Scary article from the NY Times - Driven to Distraction - At 60 M.P.H.. Honestly, I can barely flip radio stations and drive at the same time, let alone check email/voice mails etc. I suppose most people who are like me put the cell phones away while driving, while everyone else is talking on the phone or texting and thinking they're doing just fine.
It scares me I'm on the road with people who are this reckless and careless. As my earlier saga with the car illustrated this past summer, people are trying to save themselves 10 to 20 minutes but in the meantime are costing the rest of us time and as this article points out, sometimes something much worse.
The article also comes with a game to test how distracted you are while driving and texting. I failed miserably. I can't text when I'm parked and concentrating 100% on the text, let alone while driving.
However, as I said, I think people who realize the dangers have already put away their cell phones. Everyone else thinks they're invincible or better than everyone else and nothing you say will ever convince them otherwise.
