Driver aero feedback.

[Jolle]

the current aero load is as useful for a driver as the current grip level. zero. It changes so fast at braking, turning in, etc etc, that there is no time to react on some kind of gauge or buzz. Racing a car on edge is about remembering and predicting the grip levels (and aero levels) and for the aliens on the grid, that special feeling that makes them almost predict the tiny amounts of variation.

They do a couple of laps, go into the pit and they study the laps with their engineer. "in turn two it looks like the slip angle isn't yet optimal, the aero load indicates that you could gain there about 5 kp/h on the apex". Driver gets in the car and does the apex with 254 instead of 249.

By the time the flowfrom that vane reaches the driver's helmet, he'll already have an armful of oppo applied.

Weren't you the one that told me the flow goes from the front to the back of the car in a fraction of a second? Average human reaction time is ~.7 these drivers train their reaction time so .4 would be best case scenario. From the winglet to the driver's helmet is ~.5m, at 35m/s the airflow from the vane would get there just around the driver's natural reaction time.

It's the angle the flow will need to turn in order to touch the driver's helmet, not the time taken.

What you guys also have to consider is:
Do you think you can drive a car as fast as a Formula 1 by reacting to what the car is doing?
"Oh, this lap I got 5kg more downforce so I can turn the wheel 1 degree more and still make the cor..." and boom you're in the barrier.

Race car drivers drive fast by knowing the car is gonna do before it does it, if you try to react to the car you're either gonna be 2 minutes a lap slower or you're gonna crash.

As JOL says, this is nonsense. You feel a cars performance through your backside... in reality that is a complex set of inputs, feelings and subconscious reactions that are driven by the eyes, inner ear, brain etc to the car moving and sliding around.

I've no idea how the OP thinks this airbox setup would work, or what it would measure; e.g. peak downforce, front downforce, rear downforce etc. However, it would be of no use at all, as driving a car fast has nothing to do with conscious reaction times or processing information, as by the time you'd looked at something, processed what you're looking at and reacted, it would be far too late and you're off the road!

An F1 car already has a huge amount of sensors and data logging built in, and if this type of data was useful you'd see this data being shown to the drivers on the dash in real time now. But it's not, you will look at that type of data in the garage or debrief to see why your teammate is quicker; e.g. braking earlier but carrying more speed, or having a higher downforce setup leading to a better lap time etc.

Driving the car on the limit is about natural talent and feeling, hence why drivers don't want interruptions on qualifying laps or when battling with another car.
