You have to understand how the federal government works. Now that something like this has been implemented and has been successful, it’s likely that it will be adopted more widely, perhaps at the state level. An enterprising congressperson (most likely one of their aides) will notice this opportunity and pick it up as a policy/platform to run on at which point legislation would be introduced that would allocate funds or direct the federal government and/or all states to implement this. Another way is that a Federal agency gets wind of it and pilots it and then proposes to adopt it more widely.
