i agree its not simply about difficulty to overtake. its about close racing & having a chance to overtake (without an artificial 15kmh advantage, or a 1.5 km straight, or both being necessary). if F1 wants spectacle as they claim, aggressive, hard driving must be rewarded. it sounds like a big step has been made as far as the tires go, but its quite disheartening that the new regs still encourage cars to be designed in such a way that they can't chase position without turning into fat bars of soap at crucial corners.
