Traffic Co-operative idea

This is inspired by the rideshare service that has been taking off in Kauai. Discussing with some friends the other day about traffic solutions for ʻOahu, and the idea of a traffic co-operative came up as a supplement to public transport and commercially-focused rideshare. The idea being that cost of app development has dropped significantly with vibe coding (with test-driven development and deployments to provide stability), so developing apps locally that address our specific problems may be a good use of this new technology.

My thought was that developing a non-profit rideshare app focused on reducing commuter traffic time as a community could be one possible solution towards reducing aggregate traffic time. The community would set the incentives for drivers and riders, while developing community incentives (large bounties) for aggregate traffic reduction given that everyone is paying some kind of ride-fee or monthly subscription to fund incentives and infrastructure.

This would not be an alternative to uber or lyft as a destination rideshare, but something that is much more affordable for the average commuter and convenient for drivers ($40-50 month for West Side <-> UH = $120-200/mo to regularly carry 3-4 passengers) with set pickup and dropoff points for driver convenience. I feel like I can't be the only one with this pipedream so I'm posting here to collect why this would not work. I feel like various vanpool services have attempted launching in the past, so I'm wondering why these types of things don't work or if there are other co-operative types of opportunities that people think may work here.
