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.
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.
Currently, a lot of people need to drive to get to an area they would walk. Everything is very spread out.
Of course, I can also drive almost anywhere with them.
A bike path is easier to drop in than rebuilding entire cites and relocating the entire population around those walkable areas. Bike paths take years, consolidating urban sprawl would take decades, even if the political will existed.
The best way to do this is to install public transport and facilitate bike use.
