Can I define a case 1.5 situation? This is two grip-limited opposite-direction corners separated by significant longitudinal accel/braking, but the accel itself is still grip limited, not power limited. In other words not a left-right transient where the velocity is roughly constant through the whole process.
An F1 car can always generate higher G-forces in braking than acceleration. What does this imply for the ideal line for case 1.5? I think this means the ideal entry/exit width will not be an even tradeoff. There will be some asymmetry for ideal exit width vs ideal entry width. I'm not sure which way is optimum-- wide exit and tight entry, or the other way around?
I think in F1, if you have an acceleration zone between the two corners, you're always going to take wide entry and exit and diagonal the straight (barring any other hazard)... You have to get the two corners really close (e.g. fanges at Spa) before they start taking a wide entry, but a tight exit, and then a tight entry and wide exit to the second corner.
