Have you been thinking of having a "emergency central"(or whatever it's called) where you can dispatch units..? Like "alarm" buttons for ambulance, tec, fd and police.
Think some mod already has that, if you need fd you press the fd button and you will hear an "alarm" with voice and a fire truck will dispatch from the garage (eg). (doesen't remember the mod's name but that mod had like different fd alarms, like small, medium and large forest fire, small, medium or large traffic accident button and so on..).
You are referring to the latest Braunschweig Mod, version 1.7. It does sound like a good idea, it would make the game easier to handle. But Hoppah doesn't want to make the gameplay easier, he likes to have a challenge...
