aircraft that basically concluded that for some time now, the most
limiting factor on performance has been the human sitting in the cockpit.
And I think that F1 is close to that limit; at least with the current problems of porpoising.

Since when has anyone described porpoising as an advance in car
performance.
It is a unforeseen by product of design. It will get designed out.
Personally I think the FIA should consider regulations to stop cars
running with porpoising on safety grounds; or at least tell the teams
they are considering it so they act even if it means reducing
performance. F1 takes enough toll on the driver without this... and it
just looks bloody stupid for what is considered the pinnacle of
motorsport by many.
Several teams' CFD and chassis dynamics designs and remedies are a joke.

But proposing is not beneficial to performance.
I've seen the video and reports around aircraft but those balance
improved performance (acceleration, deceleration, turning etc.)
against the human bodies ability to survive the environment.
I suspect there will be a time where car performance improvements
potentially surpass our (the driver's) physical capabilities (think
g-forces on the neck) but these underfloor aerodynamic failures are
not in that category.
Or maybe they are. Does anyone have 2021/2022 same team, same track
data to show the difference between last years peak and this years
peak (with the proposing?) That would be an interesting side-by-side
video showing a lap over the two versions of a car.
FWIW DLM

I'm not sure if that would ever happen in an F1 car; I'm not a doctor, though I play one on TV. 8-)

It would be extremely unlikely; essentially impossible.
