If you’re a Transformers fan (and who isn’t) and thought the pictures of the newest Optimus Prime at the Mid America Trucking Show were wild, here’s your chance to grab a ride. Uber, the ride-sharing giant that’s transforming the call-car business ,  has announced a new promotion stunt for the upcoming Transformers 4 – a handful of lucky fans will get a 15-minute ride in the Western Star-derived big guy if they call for him on the Uber app.

Follow the directions on the Uber blog and you could be tooling down the highway with OP in Dallas today, Phoenix on June 19 and Los Angeles on June 21.  The movie opens June 27.
