Ok this is pretty sketchy but hear me out...
I bet someone has done this already However probably not a group of Porsches.
How about we get our pcars on a freeway, we take up all the lanes and gradually slow down to a stop and point the nose of our cars toward the center lane and someone (Richard) runs out infront of us while we are stopped and have stopped traffic and snap acouple photos and then we are off. Probably a 45 second thing.
