The safest driving city is Sioux Falls, South Dakota, where drivers go 13.8 years between crashes. It's likely not a stretch to assume that there are fewer distractions in South Dakota.

As for methodology, Allstate estimates that it represents 10 percent of all drivers on the road. The insurance company calculated the "internal property damage reported claims" (in English, crashes) for the 200 largest cities, using data culled from January 2009 through December 2010.
One might expect the next study to show improvement on the Kansas side based on how long drivers have been off the road and waiting at the Department of Motor Vehicles.
