1) Unfortunately I am already squeezing as much as I can get out of the existing data. The public APIs (there's a different one for each city) don't cover all fields in the General Transit Feed Specification (GTFS). I would love to incorporate more data as time goes on, I hadn't thought of sources of data outside of the public transport providers themselves, weather would be a great example to extrapolate comparisons from, thank you!

2) Yeah, I must admit there is a bias at play. Obviously there are a couple of parts of the site that have a negative spin. In an ideal world, there'd be no negative spin to create!
