this comment from that page sums it up nicely:

"What a horrible article. When you see wild swing (from 20th to 49th)... doesnt it tell you that something is seriously flawed with the survey. We didn't all of the sudden become dumber.

If 5,130 people were in the survey / 51 states (and DC) that means about 100 drivers were surveyed from each state.

Just add it to the list of countless meaningless studies that some one throws out there."
