Failure to move for sirens

[◄Chuck►]

There are differences however. Ignoring a siren is always a serious rule violation and thus cannot be an element of the actual game-play. Similar to insulting. Insulting can never be part of the game-play.

However, the things are a little different when it comes to accidents / collisions. There are plenty of scenarios where someone can act within the rules and yet collides with someone. I agree, the transition is somewhat fluent but that's just the nature of things. Also, causing an accident does not necessarily mean to be physically involved. It is quite possible that someone causes an accident, e.g. by ignoring the right of way, and causes two other cars to collide.
