Consider establishing a hub-and-spoke system, with public, mass-transportation "busses" equipped to handle wheelchairs, hover-rounds, etc. that have community stops equipped with bathrooms. To get to these "hub" areas of mass-transportation, fund or encourage the use of self-driving cars for those with disabilities to get from their homes, to the mass transit points, and then back home at the end of the day. The cars can be programmed to get them from their home to the hub.
This is a very long range goal, but the technology of self-driving cars is maturing quickly.
