Extending the Unity base tutorial with:
1. Modifying of Car Tutorial for more ‘arcade’ handling – more manageable physics needed for next step ..
2. Merging in a waypoints solution to automatically drive cars around the whole track
3. Converting from a car race to a bike race – assets/animation in Motion Builder, physics setup, some custom player control, pelotons/groups and fine-tuning the code and assets, for a solid looking prototype.

2 Weeks development for this.
