Car alarm occasionally does not work properly

[HAYASHIDASEIYAKU]

Not sure if it has anything to do with budget.
When triggered, there will only be a light effect, no sound. If there are police around, the wanted effect will be activated, but the pursuit range will not be triggered (there is no red and blue flashing area, but the position of the police car and the police can be seen). After the light effect ends, the wanted effect will also disappear.

Another issue is about the police car siren. The AI's siren sounds completely different from the player's.
