First of all, this is great. I'll definitely be using it on a regular basis for public transit and 'taxi' rides. Second, I love that you have bike directions too. BUT, the bike directions seem to be car directions when you hit the link to google maps. Please explain...
On the biking side, we're considering looking at joins between biking and other modes of transit. So for example, you could bike an extra mile and get on a different, more direct bus/train (assuming it can carry your bike).
Glad to hear you like the app :)
