Which Cities Have the Worst Drivers?

Whether explained by its large number of non-native residents or, perhaps, its confusing system of roads planned long before the advent of the horseless carriage, Washington D.C. has the dubious distinction of being home to America's most dangerous drivers. 

According to Jim Gorzelany, "Allstate studied the auto insurance claims frequency of America's 200
largest cities and found that residents of our nation's capitol were
found to get into collisions on average once every 4.7 years. This means
they're a whopping 112.1 percent more likely to be party to an accident
than the typical driver in the U.S., who wrecks his or her car once
every 10 years."

"Taken on a state-wide basis, California would seem to have the worst
drivers overall, placing five cities among the top 25, including
Glendale (5), San Francisco (10), Los Angeles (14), Fullerton (16) and
Torrence (22). New Jersey came in a close second with four cities among
the top 25, with Florida and Virginia tied for third with three cities
each."

"Meanwhile, the safest drivers can be found trolling the streets of Sioux
Falls, South Dakota, where the average motorist experiences a collision
only once every 13.8 years, which is 27.6 percent less likely than the
national average. Other top-five safest cities include (in order):
Boise, ID; Fort Collins, CO; Madison, WI and Lincoln, NE."
