Tennesse = Safe Driving?

Well, that is how the local media will be spinning it after Allstate's 5th Annual Best Drivers Report. The top ten:

1. Sioux Falls, S.D.
2. Fort Collins, Colo.
3. Chattanooga, Tenn. (21.4% better than the national average)
4. Cedar Rapids, Iowa
5. Knoxville, Tenn. (19% better than the national average)
6. Fort Wayne, Ind.
7. Lexington-Fayette, Ky.
8. Eugene, Ore.
9. Boise, Idaho
10. Colorado Springs, Colo

After driving here for five months I have to come to the conclusion that either (a) Tennesse drivers are less likely to get into accidents but not neccesarily due to safer driving* or (b) I really have no idea how bad the rest of the country drives.

Minneapolis and St. Paul come in at 39 (4.5% better than the national average) and 41 (3.6% better than the national average), respectively.

P.S. As I was looking for something regarding methodology on the study. The L.A. Times calls it an "in-depth analysis." Allstate says:

The Allstate Best Drivers Report is produced solely to boost the country’s discussion about safe driving and to increase awareness of the importance of being tolerant and attentive behind the wheel. The report is not used to determine auto insurance rates.

Uh huh. I am leaning towards option a above...

*E.g., safer driving conditions could be a factor.
