We'll share more on the Route Creator later, but to clarify: while you can only start a custom route at any of the existing routes' start locations (and there are loads of them), after that your route is basically wherever you can drive from that point-even far away from the start point, placing checkpoints along the way, adjusting the width of each as you place them. It can be a circuit or a point to point, and is not limited to using the existing road network. In truth, it gives you so much freedom that it's presenting a lot of navigation challenges for Drivatars, and a lot of resulting bugs for Playground to fix as they are finishing the game.
