It will be nice if the maker is able to put his country's flag in his tracks or the game puts his country's flag automatically do u think so
I don't think it'd be worth the time to implement, better things could be made with the time the devs have to work on the game. One of the things about Free Rider is the focus on creating, so if you'd like to put your country's flag in your tracks, the best you can do is create one.
