Had it been 20 years ago, I would agreed people were not ready for bicycles (although there has always been a decent percentage of the population who uses bicycles for transport). But in the last years, there has been a burst in pro-bike groups, activists and bike-related shops. No reason for the government not to take advantage of that and provide the necessary infrastructure to promote that change.
The only hope is that the process goes the way it went in the Netherlands, and people keep on pushing the government to make bicycles an option. See how it worked there (English with subtitles in Spanish) in this 7-minute video:
Build them, and they'll come.
