Parallel Splines

[_Aka_]

Now about switching between lanes:

• First of all, know that there is a SwitchTo method in spline controller that does (from my understanding) the same thing that your code, with the exception that it need two different splines to switch between.
  
• I think what i would have done, is to consider each road as a different spline, and lanes inside each road as different offsets, then use the SwitchTo and Offset features of the Spline Controller to navigate between different roads/lanes
