Do different occupations drive differently?

Have you ever looked at people driving cars and wonder what they do for a living?  Think their occupations have anything to do with their driving style?  It does.  Makes sense, right?  Let’s take the medical profession.  Does a dermatologist drive differently than a surgeon?  A study that focused on fast driving, luxury car owners and their medical specialty gave us the answers.  All of this information was learned during speeding traffic stops.  As it turns out, orthopedists are the fastest drivers.  Psychiatrists are next, followed by general surgeons, who are being tailgated by cardiologists, who, incidentally, drive the most expensive cars.  It makes sense that personality is a major factor in choosing professions, and those personality factors influence driving styles.  Hmmm…I wonder if NASCAR drivers speed on the interstate?
