Blue Moon [Bay], Trial [Mt], Dragon Trail [Seaside], Deep [Forest], [Citta di Aria] (city area), [Tahiti] Maze, [Sardegna] Rally, [Swiss] Alps, [Smokey Mt], etc. all have a generic title if you think about it. Either the name describes the track with an adjective, or the area the track is based off of is part of its name. It's really nothing new.
Also, not all tracks are spectator friendly irl either. Nurburgring, Spa, and plenty of others are "cluttered". And if you've ever seen a rally race, or road course, you'd know that confined courses are actually fairly common.
