This sample concerns major Asian economies, including Japan, China, South Korea and Singapore taken at different points in time in from 1960 to 1990, when most were experiencing a strong period of economic growth. Based on this sample, there is a clear exponential relationship between GDP per capita and motorization. After the $2,000 per capita threshold is crossed, the level of motor vehicle ownership, and the expected mobility, increases significantly.
