I get the impression that as long as a driver is at speed frequently that the rate of decline is less, but if you're out of the car for an extended period of time that your visual acuity declines from that of a racing driver to what a non-driver experiences.
I've noticed that most open wheel drivers begin to lose pace at about age 35. I think that HCN is experiencing that right now. He's still plenty racy, but I think you'll see that he wins fewer races than he used to, and when he does win it will be from a combination of speed and racecraft.
PT is 41, and will be 42 in December. During the last years of ChampCar, he didn't have the ultimate pace of some of the other drivers. Since then, he's been mostly out of racing. Undoubtedly, much of his poor showing is due to less-than-topnotch equipment, but I'd suspect that age and his limited schedule are part of the issue.
