Well i never knew that i have been here for quite a while, to me it was a chase and i used visual sirens aswell.

But that is not really the important bit. I think we are left with two choices here either add this to the rules or let people do what they like.

Some might do it as you described while others like me would add visual sirens. The time they will do so is limited and their aim is certainly not to break the rules at all.
In my oppinion you should leave the rules as simple as they are and let the user make the decision here. Otherwise you would have to enforce something which i would describe as nitpicking.
