Although you will only be able to experience the leader of the Autobots in truck form. By far one of the most original cross advertisement campaigns I've seen in a while.
Optimus will be in the Phoenix area on June 19th and in the L.A. area on the 21st. In order to request Optimus you must be a subscriber of UberX or UberSUV, select the "Autobots" option, set your pick up location and then press "Roll Out!!"
The joy ride only lasts 15 minutes so make sure it's a good one.!
