I've often noticed that people will not get on a tram with available capacity even though it is the only line at that stop. What is the logic here? Why stand at that stop if you aren't going to get on the next available vehicle? I've also noticed that a full tram will stop and no one will either get on or off. I could understand this if there were a traffic reason but that doesn't seem to be the case. Finally, do trams non-stop if no one is exiting (the real life "next car please" situation)? This seems to happen occasionally but I haven't seen enough to be positive about this.
