I remember seeing this app a couple months ago and being excited about a team finally doing this. They've been available in New York City for a while and now they're trying to raise money to expand to more places. Hopefully they open source the app\server in the future since it would be great to have more co-op apps for the other "gig economy" style apps.
Right, I see what you mean, so there'd be a power imbalance there. From my perspective, if drivers buddy-buddied with each other to that degree, customers would just flock back to Uber and the business would tank pretty fast. It would be more beneficial for the drivers to treat their customers well.
