looks like nonsense data to me. first, data is almost 20 years old.

"In a 1997 NHTSA study, older people made up 9 percent of the population but accounted for 14 percent of all traffic fatalities and 17 percent of all pedestrian fatalities" here we lost ages, second, under the age of 16 or so do not drive, third, sure looks a lot safer to be driving than pedestrianing. are these people driving, or does it also include people riding in the car? like i said, nonsense data.
