| Comment | I get this. My best guess is because they're extremely early stage concept designs, it's about keeping the design relatively vague. To avoid being pinned down on the detail (should things change), or causing an unnecessary stooshie early on should any single part of it be hugely controversial.
It's all fairly broad sweep at this point in time.
There's some fun though in trying to understand the routes based on what's been provided so far. There's not much to go on, as you say, but you can more or less begin to understand how it would knit together by comparing it to a real world map. |
