Assuming some even distribution of avaialable vehicles in an area, time-to-pickup scales like (area/vehicles), so the returns to scale diminish fairly quickly. And "evenly spaced vehicles" might be the worst case depending on user preferences. It might be better to have fast pickups in some places and really slow pickups in others than average times everywhere, so long as users know the pattern -- slow from my house, fast from my work etc.
