Is a Decepticon gaining on you? No worries. Just call to hitch a ride with the latest incarnation of that ultimate Transformers hero—Optimus Prime. Your way out would come courtesy of Uber. As a promotion, the ride-share giant is promising a 15-minute ride in the Western Star-derived Optimus if one selects the “Autobots” option and then taps, “roll out” on the Uber app.
