Really excited, I'm loving the mod as well
I am having a bug though, if I turn on the sirens on a certain part of the map its almost like 2 sirens turn on, and one of them travels with the car while the other stays in the same place and can't be turned off (I'm unsure if I'm describing this very well), its easy to work around though (just turn on sirens outside of that little area) and seems more like an issue with the script than anything else.
