Interesting taxi rides dataset by Danny Bickson.
From the post:
I got the following from my collaborator Zach Nation. NY taxi ride dataset that was not properly anonymized and was reverse engineered to find interesting insights in the data.
Danny mapped the data using GraphLab and asks some interesting questions of the data.
BTW, Danny is offering the iPython notebook to play with!
Cool!
This is the same data set I mentioned in: On Taxis and Rainbows
