From where the video on TV started what looks like a freeway/expressway, to where they cut the video - beating on the SUV in tied up traffic, I'm wondering how or why he got from A to B. I don't know if that freeway dead ends into street traffic or he took an exit.
If you are on a freeway with room to maneuver, stay on it! When stopped by heavy traffic, leave room in front. If it's not there, make some.
Demo derby types bash with the rear end as much as possible to stay running.
They may be able to get some swings at the windows but my car/truck will be anything but a still target.
Edit: If you decide to make room your insurance probably will not pay since it was intentional.
My wife not getting her head bashed in is worth it IMHO. YMMV
