And this is why large meets/cruises never work. Everyone bounces around passing their friends, snapping pics, cruising side by side in the left lane. They dont' want to get split up from the cruise buddies. People get fed up and do stupid shit when they get blocked in on the highway. Not to mention that highway is terrible for left lane hoggers at the best of times, adding a bunch of cars all 'driving together' does not help one bit.
With that said, Infiniti driver is a tool bag for pulling that stunt.
