Kenneth Malcolm wanted by. He sped up and tailgated a vehicle in the fast lane. When it didn't move out of his way, he changed to the slow lane, overtook and tailgated the vehicle there. That driver braked briefly so that both vehicles had to slow, eventually dropping behind the vehicle that Mr. Malcolm initially hoped would get out of his way. He moved back behind that first vehicle and continued to tailgate it. All of Mr. Malcolm's movements were made at a speed above the posted speed limit.
