Re: What the Fark???
Using raw insurance company claims data can be tricky because you'd have to separate out comprehensive from collision and then how do you control for uninsured drivers or for people who only carry liability coverage?
I'm not sure that her metric of "crashes per billion miles driven" is necessarily a good one, because in some states, you have to drive a lot farther to get anywhere than in others. "Crashes per trip" would have been a far better metric, but data is probably not available for that measure.
Some of the western states only have a few stores every hundred miles and so to get re-supplied you'd need to drive a lot farther than in eastern states for example. You could easily have fewer crashes per trip yet more crashes per billion miles driven as a result.
Also she may not have corrected sufficiently for the weather. When we lived in WY there were times when they had to completely shut down I-80 because of high winds and slippery conditions. There were times when you could be completely at a standstill yet have the wind blow your car along the icy road while you had no control over it whatsoever. I've seen 4' x 8' sheets of 3/4" plywood blown about as if they were leaves, and that is NOT from a tornado, just from a front moving through.
Based purely on anecdotal experience,
-- Salt Lake City UT had the "worst" drivers
-- metropolitan Boston area had the "craziest" drivers
-- NY City has the "rudest" drivers
-- New England has the most "passive aggressive" drivers
-- WY had the "most considerate" drivers by far.
