And here’s another interesting point. If a road runs strictly horizontally or vertically, there are no problems with determining its boundaries. However, when it runs diagonally, you can move along the road itself or one cell above its line without leaving the road. In other words, it effectively doubles in width, and this isn’t mentioned anywhere. Also, I recently watched a video where an experienced player rather daringly attacked a group of demons with a scout to avoid leaving the diagonal road – it seems not everyone knows or pays attention to this.
