"50% of the field is forced to settle for second" meaning, since they're pushing a car, they have to continue to do so knowing second is the best they can hope for.
The pack racing was a hell of a lot better than tandem racing. I still prefer real racetracks but we're stuck with four restrictor plate races a year so they might as well give us a show worth watching. I like tracks that require skill, hell David Ragan won at Daytona last year!
With the radio communications banned, that puts the tandem racing out of the hands of the drivers and in to the hands of spotters and owners. "Let's make a deal" becomes "team orders." I quit watching F1 for a reason.
The tandem racing looks those truck pulls gone fast. The best solution is to tear Daytona Superspeedway and Talladega Superspeedway to the ground and go run at New Smyrna Speedway and the Talladega dirt track. You know, real tracks that require driver skill to win and not just dumb luck.
Or race on the beach again -- I would pay damn good money to see that.
