I don't believe that there is one cause but there are strong indicators of symptoms of problems (which are many and this is one of them.)
While you are correct that the higher density counties are skewed to the left of the chart, the fact remains the National average for the ratio of bike/ped fatalities is 13% and even a lot of our rural counties have a hard time getting below that.
