That would be a start. But there are other more important measures. How many injuries along that path? If the injury rate - to both cyclists and pedestrians - on a per cyclist/pedestrian basis is increased, then this facility has measurably increased risk. That is an instant fail, no matter how positive the feedback.
Do you expect pedestrians to be "overwhelmingly positive" about this? As someone who is more often a pedestrian than cyclist, I have to say that I am very, very grateful there is no such abomination in Birmingham.
Oh... "admit that you're wrong" suggests you consider the naysayers to be wrong. It is a convenient insinuation which suggests that you are right - but without any of that inconvenient hassle of actually having to come up with anything to support that insinuation. So how about I give you the opportunity to state why do you think that you are right and "you guys" are wrong?
