Nation's Worst Roads Driven by Nation's Best Drivers

This January, Michigan has found itself at the very bottom, ranked #50, of two lists in relation to other states.  The first study that came out found the roads in Michigan were dead last as far as road quality is concerned.  

A company that creates HD maps for self-driving cars captured and analyzed video of five million miles of driving on U.S. roads and found that Michigan has the worst roads in the country while Florida has the best.

The methodology for ranking these videos included randomly selecting video frames from the videos (in total, 15 million frames sampled), and excluding all but the surface of the road from predictions by a neural network. Their neural network measures quality in four distinct areas: road paint fading, pavement cracking, potholes, and surface flatness. The data was normalized by frame density, and filtered to remove areas with not enough data.

Interestingly, this week sees the release of insurance data that claim that Michigan is also dead last in another way. QuoteWizard sampled incident data (with more than two million data points) from the users of their website and juxtaposed it to Federal Highway Administration fatality data. To quantify overall driver standards for comparison, they weighted various incident totals for each state with its occurrence percentage. The rankings are a sum of weighted means calculated from accidents, speeding tickets, DUIs, citations, and fatalities.

Their finding was that Michigan is dead last-- in having the worst drivers.  That is, they have the best drivers in America.  

Perhaps dodging potholes and paying the nation's highest insurance rates make Michigan drivers more cautious in preserving their vehicle's integrity.  Why else might this strange duality exist in Michigan?

According to the map it appears as though Lake Superior, Michigan and Huron have some of the worst roads of all. Must be those 20 ft. rollers.
