Just a suggestion: Since we don't have the radio in police car and the left directional does nothing, it will cool if we could activate the siren only with this button. Press one time ( without holding it ) for wail, press again to switch to yelp and again for hyper-yelp. The lights could still be activate by pressing L3 and the horn by holding it.
Could this be integrated with a patch? It would be cool to just activate the lights and not the siren. The siren can be annoying for a long ride.
What do you think?
