Vector proposes a solution to the high flux of automobiles hitting the roads. As the economic activity grows in Pakistan so do the cars on the roads. More business = better economy = more people in a position to afford cars.
One might suggest that the solution to the increasing population lies in public transport to a point where personal vehicles will only be allowed in the outskirts of the city. But is it just about getting from point A to point B or does owning the car have more value.
