I would think that if they want to develop the transit side of things there's a lot of coding to be done behind the scenes by them. You've got to have people pulling data from the cities that are publishing it and then displaying it in your app. You definitely can't crowdsource that part of it.
oh absolutely, it would be a lot of work. but, since Apple is now in the Maps game, they should get down in the dirt and work. similar to how they've had to create relationships with cell companies all over the world and media companies all over the world to make itunes and iphones available most everywhere. Now they should make more relationships for public transportation and offer it integrated into the app (like they used to, via Google's data)
I get the same vibe that this public transit handoff is like Apple's "sweet solution" of webapps for developers in 2008 before they announced the SDK. it's a shitty solution and not what people want or need. but, sadly, in this case I don't think Apple wants to offer the better solution. I'd like to be wrong
