 ## Primary metric
 The primary metric of this challenge is HD-Score (HUGSIM Driving Score) defined as:
 ![hd-score](https://huggingface.co/datasets/XDimLab/competition_public_dataset/resolve/main/hd_score.png)
-where the driving policy items include driving with no collisions (NC) and drivable area compliance (DAC), these subscores are crucial for driving safety. The contributory items include time-to-collision (TTC) and comfort (COM), which may not directly cause failure cases when they are low. Besides, the weight for TTC is 5 and the weight for COM is 2. The final HD-Score is averaged across all simulation timestamps and multiplied by the global route completion score R<sub>c</sub>.
