Why has the number of motor vehicles almost doubled since 1990?

The number of motor vehicles has almost doubled since 1990 due to several factors, including population growth, urbanization, and increased economic development, which have led to higher demand for personal transportation. Additionally, improvements in vehicle affordability and financing options have made car ownership more accessible to a broader segment of the population. The expansion of road infrastructure and the globalization of car manufacturing have further contributed to this rise in vehicle numbers.
