Thanks, I'm having a hard time with those indicators as well. One question. If I never set the indicators in my code, do they automatically get set? Or are the passengers getting on the car when there is no indicator?. (So far I've been having a lot of people refuse to get on my car, and I assume it's because my code is setting the wrong indicator).

BTW, this is a game that will haunt me for a long time to come. Even when I pass a level, I stay on it trying to reduce the metrics rather than accept that I "lucked out" with my naive algorithm. You did a fantastic job on this.
