I got into a Ambulance then went up to a police car my friend was in then i started my siren and it started his siren too!! I turned mine off and his went as well! I repeated this 100 times So I had control over his siren in my ambulance!!!!

I locked the SSV bridge and then I can open and close it with commands but sometimes opening the bridge don't work so I use the close command to open it and the open command to close it! Big glitch I think !
