The DOT (NPTS) data contradicts the popular notion of long daily commutes for most Americans. In actuality, of those personal automobiles on the road, 42% travel less than 15 miles each day, approximately 50% drive about 25 miles a day, and approximately 80% drive 50 miles a day or less. More surprising is that this data shows that less than 5% travel 100 miles or more daily.
