Some stories, there's just not a lot of gray area.
A few months ago, I was driving behind a vehicle that kept lurching from one side of the lane to the other. It was pretty bad. I thought the driver was drunk.
Finally, I passed the car, and I saw that the motorist was driving with one hand on the wheel, whilst her other hand held a cell phone aloft, the better to conduct a Facetime chat.
She was driving about 70 miles an hour down the highway. Yikes. Not good.
