I agree that PP is not the best choice. I thought the "filler" material last year was interesting- when they gave cost figures, team budget info, etc...
As far as hardcore tech info(ie interesting to racers), I doubt we will ever see it. If you look closely at the sport, it is just a bunch of "marketable personalities" that team owners have spent a great deal of time and money teaching them to drive these cars. Long gone are the days where a racer paid his dues and moved up on his own. I'm willing to bet quite a few of the new generation "pros" couldn't set their own timing if they had to.
