There are probably many deleted scenes for Age of Extinction, but this is one that we will know about, thanks to Kelsey Grammer in a Yahoo interview.

In a recent interview about his roles in Transformers and Expendables, he mentions that they filmed a scene of him throwing someone Chinese out of a moving car who then gets run over... but since the movie was partly funded by the Chinese government, they wouldn't approve the violent death of someone Chinese (I guess by a Westerner, as many Chinese would have been killed by the Robots at the end).

He also mentions that Michael Bay is still using "real fear" with his actors, by not letting them know how big the explosions will be.... similar to the story I read about the Scorponok scene in the first movie, in that Tyrese and the soldiers were told to run for their lives because the explosive ripple effect of Scorponok under the ground could not be stopped once started.
