I just said it is a riddle, wrapped in a mystery, inside an enigma.
Put even more simply, accident "statistics" are far from perfect. Hardly
a "paradox."

Overall accident statistics for the USA are very reliable, since they are
reported by police, insurance companies, and by individuals.

The numbers are high enough, and consistent enough, to make the error
only a very small percentage.

You won't get *better* data that the census bureau data on accidents in
the USA by state - and none are showing what we'd expect.

Hence the paradox.
Where are the accidents?
