New Routes/ Maps

Looking forward to new routes and features due to be implemented. However I cannot understand why Zwift are not capitalising and expanding on UCI courses/ National Championship courses, Classics courses, Vuelta, TDF and Giro routes.

maybe issues with getting rights etc. (prolly have to pay the organisers to use a real world route virtually, or set up some other kind of arrangement)
vast majority of zwift users are not interested in racing, just training, and you can do that on any route :3
