Good idea, but unfortunately for now it's useless for me as I can't really see my position during a race when in a pack of cars. What I suggest is to update the app, so the player position is rendered on top of any other car, so it's always visible. It would also be nice to have an option to turn off the background colour completely. I see that the finish line is a .png file, would be great if car arrows were image files as well so people can modify it looks to their liking other than a colour in the config file.
The background is now set to transparent by default (editable via the settings.py), thanks.
Having the triangles be PNG's is a great idea! I'll have a look to implement that in a future update :)
