L 20

L_20 is a hidden track found in Gran Turismo 2. It is an invisible slalom license test track. The collision is present despite being no modelling present here. No AI pathfinding is present, so the AI cars can not race properly here. The track also has it's own course map.

This track can be also found in the demo versions of the game. However, there are no differences regarding this track between the two versions.

Bugs and Glitches

 * There is no AI pathfinding. The opponent cars will simply stand still when loaded.
 * Interestingly, the track "texturea" and "drivtype" files are undefined, causing an invisible course. Collision, however, is still present.
