Sort of. It provides a great online source of designated bike routes/lanes/paths in cities. From my experience, this news is an incredibly sharp double edged-sword.
Good news first:
One stop shopping for all your bike directions.
It relies on city-data that is...hopefully up to date. Many existing municipal routes or "class III" (in CA) were first installed in the 70's during the first bike boom. A good amount of these routes were slapped down willy nilly and now find themselves on major arterials. There's nothing "routey" about them.
Also, it could make people think that because their destinations aren't served by a complex network of bikeways, then it's impossible to access their destination by bike.
So it could give people a false sense of security, at least to the ill-informed. But it could also encourage a lot of people out there to start riding their bike. Hopefully, the latter.
