Possibly, this short 10sec replay thru T7 at Road America illustrates demonstration of straight line sliding thru a turn?
Note the only purpose of very slight drift is to rapidly change line to project a vector inside a point further ahead, such as the second large tree on the left coming down to T8.

Only have imagination and usually dubious intuition.
Really like to know if it doesn't show that and if not then what is happening?



This clip is best viewed from high up directly above car.

:)

Latest Edit: added a composite of screenshots from clip that show tire marks indicating line of the drift.
(clik ctrl+ a few times for better viewing).

Sort of just a housekeeping update...too late to edit above post.

Plus this is new...


Infinity is a variable of a generic 4D straight line net within which the racing line between nodal points is established by consequence of circumstance at any moment. So while the basic points are conveniently diagrammed with the typical 2D diagram of a 90deg turn, for any and all turns the net is stretched by parameter definition, (to reveal maybe a Broc curve or P-curve?), and set with certainty the minimum line between the driver and a specific point on the far side of any turn.

It is a net that is mentally projected across the driver's view ahead like an overlay in motion.

The lines are not measured because only the locations of nodal points are significant.
Cars ahead are nodal points and relationships between them are absolute regardless of speed or distance.

When a racing car is "in slip" and on the edge of maximum lateral load the reality of its line more closely reflects the purity of the ideal, such as a certain most efficient trajectory, whether named or not...as it seems in skiing, sailing, flying, surfing, skateboarding...simracing.

The housekeeping update referred to in the above post is for the pic in the prior post.
:)

And here is sort of done with it something new...just trying to figure it out.

I think John's saying the fastest way through a turn is the longest way.

I know what I'm saying?
It is still as its always been questions and guesses.

Do agree the longest line, (widest arc that touches inside edge of track), is in theory at constant speed the fastest line thru a flat 90deg turn. Do know from reading Paul Frere the racing line is the line of least resistance.

From very very little understanding of the physics of the lines made by things like Earthly projectiles on piloted or not trajectories, given magnitudes that exceed 1:1 steering capability, while near maximum lateral load, well into slip, (leading edge tire distortion), with the wheel held steady, that weight balanced asymmetrically will control the direction of a car, and by anticipation and throttle, a driver may determine it's line exactly.

The apex of the racing line is the point along the car's line of travel when/where the sprung weight quits moving out and before it begins its return to center.

Ideally weight should shift out only once and return to center only once per turn.
It should be the minimum off center shift of weight.

The car goes where it has to go.


Thanks for your comments btw.
:D
