seems to be the right place to find stats about driving fatalities.

"Note: NHTSA estimates alcohol involvement when alcohol test results are unknown.
*Total Number - Total includes fatalities in crashes in which there was no driver or motorcycle rider present."

cars are crashing with no driver present? dang, they're just like those loaded guns that go on a rampage and kill their owners.
