@Claudia_Sahm @Noahpinion @rortybomb ~487 cars per thousand people in 1966, over 840 by 2008:
The graphs below show the number of motor vehicles per thousand people for various countries. The data for the U.S. are displayed in the line which goes from 1900 to 2008. The points labeled on that line show data for the other countries/regions around the world and how their vehicles per thousand people compare to the U.S. at two different points in time, 1998 and 2008. For instance, the top graph shows that in 1998, Western Europe's vehicles per thousand people was about where the U.S. was in 1968, but by 2008 it is about where the U.S. was in 1972. The lower part of the graph (1900-1940) is shown enlarged below the first graph.
