yeah i do understand your point, the porsche races were very cool indeed and that's the point: they were all different.
This was that thing i loved, porsche was not less interesting than gp2 and gp2 less interesting than F1, they were all different.
let me express myself on that example as i think this is where auto racing is so interesting by its diversity (while fundamentally running on the same track, the same day).
An F1 car and other series differ on two points(racing wise): frame of driving, and time compression.
frame of driving:
Porsche GT cars are hard to drive, you have to master the car itself first then run it at isane speed.
On the opposite an F1 car (a modern F1) is easy to drive and can be pushed to the limit.
What's the difference? the F1 car , km/h for km/H , will go farther into the limit.
This is like, i ask you to walk in straight line from a point A to a point B.
The Porsche car would be a man that is drunk or have any infirmity preventing him for going straight.
Thus if a competition was held between drunk men, the best would be the one being able to exploit the more its possibilities.
The F1 car would be a man that is an athlete with its almost full potential ready.
If a competition between those men was held, the best would the one that has the best line the best potential.
There's then a difference of competence the porsche driver uses his skills into his car mastering, his frame is thus the car, the F1 driver use his skills on the trajectory, the accelerations, thus the frame is the track.
The drunk man can be the best at controlling the effect of alcohol , he will never go straight then will never be able to be as quick as the athlete, still one can be impressed by skills of achieving some times while drunk.
This is my answer to the "F1 cars are too easy to drive now! pilots don't do nothing!".
The time compression:
What is obvious, is that F1 car run hell faster than anything else on a track.
The best gp2 lap time was 1:59 while F1 were 1:48 (on race).
Clearly than means, in corners, they spend less time in them, they also accelerate faster, and brake later.
With this, the tires react faster than on anything else (a slip angle of 3° gives an F1 car its maximum sideways acceleration).
What that means? first, when a pilot is 0,5 secs ahead of someone he did perform A LOT better.This would, in GT racing, corresponds to a 8 seconds gap or something like that.
Second when they make a mistake, the mistake cost them less time (because they spend less time in the corner)...except if they slow down!!
A slow down in F1 cost more in gap than in any other racing series.
That"s why on TV you see replays of pilot running a bit wide.
If you look at the other series, you'll see that anytime and nobody notices it, in F1 running wide costs you a lot of time.
The rate of change of the state of the cars is also so fast that it requires a lot of fast decisional processes for the pilot.
F1 pilot are brain-shaped, their brains are trained to think a certain way which goes as far as re defining some unconscious processes.
The blasting accelerations (both in cornering and braking/accelerating) associated with speed means that you can have a lot of cornering speeds.
This was obvious at spa.
You can turn 20km/h slower at the apex than your competitor and still being the quickest in this corner (because of braking/accelerating possibilities, and the cornering transient performance).
Well i'll stop here, what is want to say is that speed brings a lot of physical consequences that make the driving of a current F1 car totaly different of the one of a Gp2.
So imagine the rest...
In 92 the cars were not in this way, this different now, but i think if you want to see that, then GP2 is good.
That's why i want to see F1 cars being fast in corners, braking supra late, accelerating like hell and being missiles in lines.
Just so that F1 is different (like nascar is different from IRL).
