Between 1 and 7 p.m. today, you can be picked up by Optimus Prime. More or less. Less, mostly. But more than usual, definitely.

As part of the promotion for the fourth installment in Michael Bay's Transformers series, the flame-specked semi is roaming Dallas.

You need Uber to do this, though. So, if you already have the app, open it up, select the "Autobots" option, tap "Set Pickup Location" and then "Roll Out." According to Uber's blog, you'll have 15 minutes to ride around in Optimus.

If you think Uber is sketchy, you're out of luck. No word yet on if Megan Fox or Rosie Huntington-Whitely will be there as well.
