By this measure, vehicle miles driven are off 3.6% Year-over-year (YoY); the decline in miles driven is worse than during the early ’70s and 1979-1980 oil crisis. As the DOT noted, miles driven in December 2008 were 1.6% less than December 2007, so the YoY change in the rolling average may start to increase.
in other words, things are still getting worse. They’re not even getting worse more slowly. All the graphs together in one place make for a pretty frightening gallery.
