The footage with the girls, while incredibly awkward, is nothing more than a flirtatious conversation. Now, fair enough that the driver realises he has the CEO of Uber in his car and wants to talk about his situation as a driver, and I give props to Kalanick for actually taking the time to listen and explain.
Did the ending clip not paint Kalanick in the best light? Sure, but keep in mind that in this situation he is a guy in his private life who has been blindsided and accused of ruining this guys life, with, what it seems like from other posts here, lies.
If telling the guy he needs to take responsibility for his own choices instead of looking to blame someone else is the worst thing that Kalanick could say to anyone, then there really isn't a story here from my point of view.
Also, Bloomberg should really take a good hard look at themselves for posting that video without cutting out the conversation with the women. Posting that section of the video is the kind of disgusting shit that TMZ and other gossip rags would pull.
