In the early '80s, miles driven (rolling 12 months) stayed below the previous peak for 39 months.

Currently miles driven has been below the previous peak for 44 months - so this is a new record for longest period below the previous peak - and still counting!

The second graph shows the year-over-year change from the same month in the previous year. The current decline is not as a severe as in 2008, but this is significant.

With the slowdown at the end of July and in August, miles driven will probably decline further in August.
