Thanks for this API, I really like it. However, there are two problems I have encountered so far, which are: 1.I have one problem encountered which was about the broken down vehicle, when I arrived the car scene, there was not any instructions the guide me through how to deal with this.Therefore I had to restart the game. 2. Secondly, this is about illegal car race, when I have arrested the the suspects, their cars still at the scene as they would not disappear. The cars would be stay there forever.
