Once the ride-sharing aspect of this app is developed, I feel like this app (or a connected service) could potentially be expanded to help improve the lives of people with disabilities in other ways by connecting them with people who want to help them live fuller lives. In particular, I'm imagining a way that volunteers might connect with people in need. For example, I might be a person who could use help blowdrying my hair once a week. Perhaps there is a Pittsburgher looking for a way to give back. I could post my need and be connected with the volunteer. There are, of course, certain risks to take into account with a program like that, but allowing access for volunteers on an institutional basis (through synagogues, churches, boy/girl scout groups, schools, corporations, etc.) could help to alleviate some potential concerns. Just thought this might be an interesting "Phase 2" or "Phase 3" of the ride-sharing aspect of your app!
Ride-sharing has become such a key part of transportation and has replaced or supplemented taxis and buses for many people. It has become an essential part of our cities' transportation infrastructure. That's why it makes sense to ensure that all people can reasonably access this kind of service! Great idea + certainly the wave of the future.
