The feature you’re looking for Roblox to implement is predictive pathing. Your first example (the drawings) demonstrates in a 1 dimensional way. Car A being ahead of Car B in a straight line.
Unfortunately things get more complex of course when trying this in all 3 dimensions for say example, a Plane game.
This is something I’ve been trying for, for quite some time but the answer I’ve usually got is that Roblox will not be spending time and effort towards this (at least any time soon)
