For the people with lag:
I Did some tests with the siren script and I was right, the hidden dummyobject NEVER got deleted. So, when playing for longer times it MIGHT cause some lag because 100's (if not 1000's) of these hidden objects spawned. I have fixed that and here's the new script. See attachment.
How to install:
1. Unzip the package
2. Move LASiren.script to your '...\Mods\Los Angeles Mod v1.8\Scripts\Game\Command\' folder and overwrite the older file
3. Done!
I am not sure if this fixes the lag, but it's a start.

Thank you. I will certainly try it now because I was having problems with the siren script. I'll tell you if it works in 2 hours.

Wow! What a world of difference. I don't get any lag when playing freeplay for extended periods! Thanks a lot Hoppah!
I hope you include that script in 1.9.
