The online racing simulator
It is the drivers job to actually make the racing clean, not the admins. The admins set the guidelines in the rules book(s) that they publish. The drivers need to at least skim them to get the gist of the message, and then display on-track that they know what the admins want. They set the guidelines by any event description texts, any briefings issued, any final notes in the moments before a race start.

But all drivers have an automatic duty to know basic principles of racing (e.g. Don't bat someone off, don't shortcut the course, avoid contact where possible).

The admins have an automatic duty to know how to apply appropriate penalties when a driver strays foul of where they want the conduct to be. Control early, and you are likely to break the bad issues from happening again.

I know this all too well. Over NDR's 5 years, we have gone from cases like this (See 2008 Kyoto 250 :nod to having now established (and usually respected) guidelines that the racers follow.

Before anything can become great, it has to do the trial and error. As more people do it, it does get easier. It's called evolution, and learning from those who came before you. Nothing beats proper experience, however.
