Because the infrastructure (and the vehicles) is very expensive and there
has to be a level of market for it in order to return a viable benefit-cost
for the project. That's why we apply the appropriate transport solution to
the appropriate circumstances. It wasn't so different in the old days when
lines were built in anticipation of development and when the development
came, before the automobile age, there were plenty of people using the
public transport. Now, with more people driving themselves you need a
larger population to provide a viable patronage base.
