Rules regarding exiting units

[Herr Straße Laufer]

Should we all play it that way at all times, or is this an informal ROE that can be optional and agreed on at game start?

Forcing players to not exit units from the map is not a good move. Common sense ROE's seem to be in order?

Scenario/map function and comments can tell players they cannot exit units from the map. It will avoid playing by supposed ROE's that do not exist.
Communicating with your opponents seems a key to success and better understanding?
