Bing's Physics is a modification for GTA San Andreas that changes the surface physics. It replaces the surface.dat file with a new one with different values of friction coefficient. The modification has two variations: improved and standard.

- The improved variation is the surface physics from ChatGPT and Bing. It is more accurate and detailed for each surface.

- The standard variation is surface physics only from Bing. It is more realistic and general for each surface.
