According to the SDK:
Several empirical/experimental tables are set in hard in the code to provide friction and braking coefficients Cside friction, Crolling resistance and Cbraking resistance depending on:
- the type of contact (eg: wheels, skids, scrape points, etc...)
- the type of surface (eg: concrete, snow, grass, etc...)
- the surface condition (eg: normal, wet, icy, etc...)
Please reveal the values contained in these tables and allow developers to change them. Also, provide information on the source of the values currently being used.
