People who drive while texting, reading, talking on their cell phones and eating. When you are driving, just drive. Maintain a bit of situational awareness and, for God sake, respect other drivers.
Today, as I was driving into my office (I have a 40 minute commute each way) I was cut off or otherwise had to alter my course because of another Inattentive driver. The ironic point to this is that I am ADHD-Inattentive Type and I was being very focused on my driving while others were not.
So, whenever people are driving, they should just DRIVE! That is all.
