When you select the 'free roam' button, there should be a 'toggle invisible walls' button and player can click yes or no for the walls. Say, for example, if somebody wanted to explore the areas past Lindau-Aeschach, they could just toggle the switch to turn ithe invisible walls off.
Invis walls stop the player going off the map.. I would rather see a similar togglable option for red signals and have the ability for all points to be controlled by the player like the manual ones
