During the climax of the film, when Larry, Ahkmenrah, Huns, Nick, Rexy, Jed and Octavious chase after Cecil in the park, Jed and Octavious are driving the RC hummer. Question is, HOW DO THEY OPERATE IT! Even if they manage to get inside it RC cars can't be operated on the inside, they requier a remote control, hence the name. And even if they figured out how to get inside the car and turn it on, how does Jed know how to use it? Same at the end with the RC car.
