Transformers: Revenge Of The Fallen - They Have Drivers!?!?
When Sam was talking to Makayla by the campfire about turning himself in to the police, bumblebee transformed back into the car and Sam leaned up on him the engine was reved up and the shot panned out you could see the driver of the camero moving around.
The only holograms that they showed in the whole two movies were the decepticons and the motorcycles, Plus the driver in the car moved side to side and in the next shot there was no driver. Still the same scene but no driver. Now i would agree with you but even in the first transformers bumblebee and all the other autobots never once had a hologram driver.
The only reason they put holograms in them is to make humans think there is someone driving. Sam knows bumble bee is a robot so there wouldn't be a need for a hologram.
