One other piece of information is the Mad Max truck from Chicago was spotted, not sure though if part of filming or just attached to the traveling filming caravan. The vehicle is rumored to be Megatron, something that "Astrotrain" reported to me as true:
Megatron is for a fact the Mad Max semi in TF3. I can send you more behind the scenes pictures from a storage facility where all the vehicles were kept while in Chicago. My father in law who works for a special effects company in Chicago was one of a group whose job it was as he said Michael Bay states "make this truck look more demented." Also not sure if it is known or not but Patrick Dempsey’s Character is a super Billionaire computer expert, who helps the transformers buy building additional ones to help. Those NASCAR transformers are not partially transformed those are ones he created, along with he "power glove" we have seen Sam wearing.Below are links to multiple galleries of the cast, the Transformers vehicles, sets and more that are worth clicking to. Below the few sample pics is also the news report from Fox5 that includes their footage of the accident. Of note the driver of 'Bee is uninjured, they believe the cop is ok but not verified, the area was blocked off in various ways and yes production does have another 'Bee they can use. Thanks to Katie, bjoneill, YoBoY, Y2G, and Astrotrain for the links and info in this post.
