Attention! The second version has been released, you can download it from here!
Now it will be possible to meet an ambulance / fire / police going to the call. Some go quietly, some rush like crazy - for example, for an ambulance, which is in the screenshot, I barely kept up. It is possible to identify cars going to a call by the included siren. The script is made in an attempt to revive the game world. In Watch_Dogs and GTA V, you can also find such an event.
Each city spawns its own cars and peds inside them.
Version v 2.0 - Normally configured spawn cars, they now appear on the roads. - At the ambulance, the sound of the siren is taken from GTA VC.
