>>2057440The main advantage is not being held up in traffic.
Sure that TECHNICALLY can be done with bus lanes but cage-driving retardoids will hog the bus lane. That does not have the sense of impending doom that hogging the tram track does.
The best way to speed up your transit vehicle is to have it in a separate, dedicated lane that cannot be blocked by retards.
As such, the logical conclusion for all public transit is, and always was, the suspended monorail.
But they don't want you to know that.
