As I think about it, I'm actually surprised that the bulk of trips aren't on the other side of the line, namely because speed isn't CaBi's only advantage.

1. Cost - The marginal cost of CaBi is $0. Whereas riding transit costs more for each trip. So users should be willing to take a little bit longer to get where they're going because it will save them money.

2. Exercise - On average, people value exercise. That's why they invest resources like time and money into it. People should be willing to take a bit longer to get somewhere via CaBi because it frees up time for exercise.

But then again...

3. Presentation - working against this is that many people don't want windblown hair and sweat-soaked clothing based on their destination, so this might dissuade members from biking, event when the above factors would make it desirable.

4. The Blockbuster effect - In a group, taking CaBi might only work if everyone is a member and everyone wants to take the trip. It's possible that even considering all of the above factors, members choose transit to stay with friends.

Still I would expect 2 and especially 1 to far outweigh 3 and 4 and so for the bulk of trips to be above the line, not below it.
