Not that I'm disagreeing with the overall trends, but has anyone looked at how types of trips have been changing? An overall drop in automobile VMT could mean several things - e.g., a reduction in total trips, a reduction in the number of short distance trips, a reduction in longer-distance trips, a reduction in trip lengths of all types, a reduction in trip length for longer trips, etc... It could also mean people have become better at how their trips are chained, so that their trips begin at home but cycle through several destinations without returning home as many times in between as before. And it could represent mode shifts to transit for certain types of trips.

This is all relevant to designing, as the last line of the article says, "transportation policies that suit our needs in the 21st century."
