That's interesting because the article says the opposite, that supply (mostly) proceeds demand when it comes to mobility infrastructure. The fact that demand is showing so readily indicates there is much unrealized potential there.
It's called "induced demand" when people don't like it - but for almost all transportation you need the supply before the demand because there's not really any other way to go about it. You can try to work out where people are currently traveling and build on that, but it's such a feedback loop it may not work.
One of the most common examples I know of is building a metro line to "nowhere" (e.g. a few stops past where it ends) - in 5-10 years that will be a bustling area because now it's connected.
