Camera follow the hex path.

Maybe this short tutorial I made a long time ago will help:

Start by converting the Hexagon shape layer to a path by right-clicking on the Shape Layer/Contents/Polygon, then follow the steps in the tutorial to attach the camera to the path.

You can copy & paste the path directly to the relevant properties after converting the procedural polygon to a regular path. Yes, you can parent stuff just as well based on that. in any case, it's gonna look garbage. That's not how human perception works and from a mere technical viewpoint the sharp corners are going to cause bumps. It would be better to hand-animate the motion similar to how the car would move along the track hovering from left to right based on the forces and acceleration.
