Cell phones, mirror neurons, and driving

Recent research has suggested that driving while conversing on a cell phone is more dangerous than doing so while speaking with passengers. The researchers suggest that passengers, by paying attention to conditions on the road, help drivers to pay attention at critical moments, thus mitigating the distractions that conversations cause. This seems reasonable. I would like to suggest an additional reason that phone conversations are distracting: humans’ ability and tendency to imagine the world through others’ eyes.
