Last year they were playing Symphonies and national anthems with the engines,(I think ,not sure because of the secert)They change RPM's with a key board to play the tune.That was on the Renault's web site.All these major changes have only really come about in about the last 15 years or so.Before that they were just fast cars.Really its the rules that keep me watching.Dale jr cant win when he runs low on gas,sets a full coarse yellow,then runs down below the line and just barley has enough gas to drive slow under full coasre yellow to take the checkered flag.They use the black flag for that crap.As a rule they just pull over and get out of the way and let the race continue.A yellow flag means no passing.If you do then you have one lap to surrender it back.Or your out with the black flag.
None of this driving your wheaties ad around in low gear.
