I have a newly minted 16-year-old (male) driver in my household. Over the months that he was only a permitted driver, he asked good questions while he drove and I passengered. Inevitably, we discovered, the answer to the frequent "What is that driver up there DOING?" — the driver who was poking along 10 mph under the limit causing mayhem, or the one who was drifting over into our lane, or the one overcorrecting after a meander over onto the shoulder — was either texting or chatting along obliviously. Stop it.
