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.
