The video shows filming in a highway portion as cars suddenly peal out of the way to probably avoid a CGI Transformer. After that it shows a massive looking explosion with debris flying everywhere. Pretty cool looking.
In addition he provided more pictures of vehicles including a blue Chevy Volt. In the third vehicle you can see what might be the same car (or just another prop car) as it crosses an intersection. The last picture is more of the aftermath of the explosion from the video.
Thanks to Gettodeath for the video and images.
Update: Removed reference to Volt being a prop car (as probably isn't) and also added below pictures which have been enhanced by Keith (thanks!) to better show off the vehicles details.
