The Challenge Brief mentioned "resource deserts." When a pet owner finds himself/herself in such a resource desert, he/she needs affordable transportation to resources that are located outside the "resource desert." Often, owners may not have their own transport, and taking a large pet in public transport or a taxi might be problematic. Typically, pet welfare orgs have tried to help out by arranging rides given by volunteers...yet, that process can be inefficient and time-consuming.
When transporting pets and their owners (especially with sick pets) is problematic, arranging for volunteers and well-wishers to provide rides is a hit-or-miss. It also ties up time and energy of the staff at animal welfare organizations, and sometimes causes exasperation in pet owners while they wait for help to be arranged.
Ride-sharing like Uber/Lyft/etc deploy highly-efficient processes for matching ride seekers to ride providers. My idea is that BFN volunteers & animal lovers who are willing to offer rides can register as drivers under a special non-profit (nominal cost) ride sharing program providing low-cost rides to/from pet welfare locations. Fuel cost, distance, ETA etc are reported seamlessly. It's great PR & customer expansion for Uber etc, a scalable community campaign, & a leap towards No Kill."
