For future-proofing your cities, and for any contributions you make to the game, make sure to realize that the scale is off in the first release, the automatically generated city by default, is just a test environment, it is not to-scale. In later versions the scaling of the roads and such will be increased. I repeat, 1 in-game unit in the world position coordinate system, such as with the variables pathposx or buildingposy in the source code, corresponds to 1 meter SI.
