While I think a well-functioning service like this is useful to end consumers, I'd be surprised if the successful ride networks are supportive of having 3rd parties get in between them and their consumer dispatch (is that why Uber is missing?).
This reminds me of Corral Rides. @snirkodesh and team pivoted to Hitch, "an affordable way to get around SF by sharing your ride."
Are you planning to continue working on this, @ohnobackspace?
Report
I love the idea @ohnobackspace and have toyed around with it myself the past, but have the same thoughts as @deekay -- you're at the mercy of the provider, and they're not incentivized to let you hook into their network and give their users alternatives. (at least at this point, may change if things flatten out a bit).
