Just my opinion...but... If the race director is making most of the calls, that's a big part of your problem. The race director's job is to keep the show organised, flowing smoothly, and running quickly and efficiently. Most rulebooks, under the procedural rules (which few people read) state that the flagman is in charge of the track. They also usually say that no protest is allowed on the Flagger's decisions. It doesn't say no protest allowed on the race director's decisions. If the race director is running everyhing, as a flagger I would help them wire the track for green, yellow, and red lights, tell the competitors that lap flag and black flag calls will be coming through the one way radio, and walk away. Good race directors (and I've known a few) will not make competition calls unless it comes down to no other choice.
