First off “Africa” (22.2% cars) and “Australia and New Zeland” (75.9% cars) are not shown. But probably more important: The paper where the data is taken from used the traffic data from 794 cities, “weighted by the population of each observation”. Most probably there were more cities from regions with high car usage in the data.
Interesting side fact: “The 794 cities in the data are not representative samples of cities worldwide or different regions”.
How did they get an average of 51% for cars, when all but one bar is below that?
