I was thinking maybe someone could make a mod that makes a customizable bus sign so it wouldn't always say 'Not in service' all of the time.
This actually can be done already, albeit in a kind of clunky way. Open the console (tilde key), select the vehicle lua in the dropdown menu, paste this into the text box: controller.onGameplayEvent("bus_onRouteChange", {direction="direction", routeID="42"}) and simply replace the text that says direction inside the quotes to whatever you want to write. The routeID part is for the icon on the left of the display. For example, this looks like controller.onGameplayEvent("bus_onRouteChange", {direction="custom text!!!", routeID="[bng]"}) You can do icons such as the BeamNG logo, a bus, and a plane by doing [bng] , [bus] , and [air] .
