Actually, there is an inverse relationship (I think) between the mechanical and financial "freedom" and the ability of the winners.
Simple: spec series are for drivers, free specs series are for mechanics (and rich team owners). The "middle way" is, as usual, an art, or so said Buddha.
Please, don't think I'm a Buddhist, but if you watch the symbol of the "eightfold path" you can conclude the inverse: Buddha was a fan of racing.

Talking to some of the other drivers and engineers, it’s clear the way the cars have evolved has resulted in aerodynamic and tyre characteristics that suddenly fall off a cliff face once the vehicle gets beyond a certain angle of slide, leaving drivers looking silly.
The teams are generating huge amounts of downforce as the designers search for ways to improve their cars. The various bodywork blades and curves twist and turn the vortices to reattach the air back on to and underneath the car to generate what is referred to as negative lift, or downforce, which is why an F1 car can corner five times harder than the very best road car, but if the airflow stalls from one area, the rest tend to follow at a critical point.
This is having an impact on the racing, too. In Malaysia, Hamilton was on Mark Webber’s gearbox for most of the race despite being seconds faster in free air. Salvation is on the horizon with new, cleaner aerodynamics for 2009, with less downforce but more mechanical grip from slick racing tyres. That is how a proper racing car should look anyway.

Human tolerance to g-force
Human tolerances depend on the magnitude of g-force, the length of time it is applied, the direction it acts, the location of application, and the posture of the body.
The human body is flexible and deformable, particularly the softer tissues. A hard slap on the face may impose hundreds of g-s locally but not produce any real damage: a constant 15 g-s for a minute, however, may be deadly. When vibration is experienced, relatively low peak g levels can be severely damaging if they are at the resonance frequency of organs and connective tissues.
To some degree, g-tolerance can be trainable; and there is also considerable variation in innate ability between individuals. As well, some illnesses reduce g-tolerance, particularly cardiovascular problems.
Vertical axis g-force
Aircraft in particular exert g-force on the axis aligned with the spine. This causes significant variation in blood pressure along the length of the subject's body, which limits the maximum g-forces that can be tolerated.
In aircraft in particular, g-forces are often towards the feet, which forces blood away from the head; this causes problems with the eyes and brain in particular. As g-forces increase Brownout/greyout can occur, where the vision loses hue. If g-force is increased further tunnel vision will appear, and then at still higher g, loss of vision, while consciousness is maintained, this is termed "blacking out". Beyond this point losing consciousness will occur, also sometimes known as g-loc (loc stands for loss of consciousness). While tolerance varies, a typical person can handle about 5 g (49m/s²) before g-loc'ing, but through the combination of special g-suits and efforts to strain muscles—both of which act to force blood back into the brain—modern pilots can typically handle 9 g (88 m/s²) sustained (for a period of time) or more (see High-G training).
Resistance to "negative" or upward gees, which drive blood to the head, is much less. This limit is typically in the -2 to -3 g (-20 m/s² to -30 m/s²) range. The vision goes red and is also referred to as a red out. This is probably because capillaries in the eyes swell or burst under the increased blood pressure.
Humans can survive about 20 to 35 g instantaneously (for a very short period of time). Any exposure to around 100 g or more, even if momentary, is likely to be lethal, although the record is 179 g.
Horizontal axis g-force
The human body is considerably more able to survive g-forces that are perpendicular to the spine. In general when the g-force pushes the body backwards (colloquially known as 'eyeballs in') a much higher tolerance is shown than when g-force is pushing the body forwards ('eyeballs out') since blood vessels in the retina appear more sensitive to that direction.
Early experiments showed that untrained humans were able to tolerate 17 g eyeballs-in (compared to 12 g eyeballs-out) for several minutes without loss of consciousness or apparent long-term harm.
