Uber is still growing its business as a disruptive (sometimes controversial) car service app, but in the meantime it continues to push the envelope on what else it might eventually do with the logistics infrastructure it is also creating. The latest development comes by way of Chicago, where Uber is now laying on busses with DJs and drinks. Yes, it's bus bumping from Uber. Uberpalooza will feature DJs Dante, Bobbylite, Megan Taylor and Andrew Hayden, and is being run to coincide with the Lollapalooza music festival taking place in the Windy City this weekend. Those requesting the service will be charged $50 for 25 minutes or 5 miles -- whichever comes first (so pick your traffic-clogged streets of Chicago carefully). Up to 10 other people can join in on the party bus -- as long as all are over 21.
