"Les courbes sont ignorées dans le calcul" qu'est-ce que ça implique? Pendant cette distance, est-ce que ça roule à pleine vitesse? Ou à une vitesse minimale?. "calcul cinématique simple", dans le cas des courbes trop abruptes? c'est quoi le calcul?

Ce serait bien d'avoir l'option lissage.

"GeometryResolutionWarningAlmostStraight": "La géométrie du parcours semble être presque une ligne droite sans points intermédiaires. Veuillez valider qu'il n'y a pas d'angles de plus de 10° entre les stations. S'il y a des courbes, veuillez dessiner la forme du parcours aussi précisément que possible."
