Vehicle to people ratio as a percentage figure. Read as 2.9 vehicles per person.

The projections for 2025 /2030 appear unrealistic since vehicle volumes are almost double /triple the polulation, which is highly unlikely. Saturation might occur around the 100% mark if PT continues to remain poor. If PT improves, it might reach around 85-90% & stay there (this is only a guesstimation:)

If we can find data we can use it here

Here is the data on which the above chart is based. Population growth is from reliable sources but Vehicle growth has been calculated on 11% constant growth. The graph will need to be readjusted as the growth may slow down after saturation. The saturation needs to be determined. Will update if I get those numbers.
