Translink is being brilliant by playing the cards the way they are, let the nimbies think Broadway is a preferred route, the'll get all upset and yell and cry, Translink turns around and says okay okay you win, we'll use 10th ave instead. Nimbies think they've won and Translink execs do high 5s in the back room after the meeting.
Of course this isn't the case, I'm sure there are no politics involved in any decision.
