"Metro" literally can't run on regular roads. The specialised buses are too big to fit in normal lanes. It can only run on dedicated BRT routes. i.e., dedicated tracks.
But more so I'm just angry at the misleading marketing. It's an ok project with the wrong name. And other more substantial problems like already decreasing the promised frequency, giving up on level boarding and off-vehicle tap-ons. But it was the name that I was trying to highlight in my earlier comment.
