Police siren broken?

I have noticed that when a AI policecar decides to pursue a car, it kind of blares it sirens a few times then it starts the pursuit. But when that blaring happens, all of the other nearby AI policecars do it at the same time. I dont know if it is somekind of a bug. But it happens after the new update dropped. Has anyone else noticed this happening?

 

I've noticed that too since the new update, especially when I'm in the police car and AI is driving around. The siren doesn't want to turn off, it can be annoying, especially if you have your own police chase set up with Script AI and traffic on, it messes up the siren when another AI wants to run.
I feel like there should be an option to turn off the auto siren or just not have it to begin with. I'm surprised there aren't more people that have noticed it.

 

Was just about to report this problem, lol. If I crash into an AI car while driving a police car, my siren and lights will toggle on and off a bunch of times. It also affects AI police vehicles as well.

 

this happens because you are pulling them over, or they are signaling you to pull over.
