Example Input: Ok, now we're back to my point.  Unfortunately, it is apparent that pedestrians (and probably bikers too) need explicit instructions to help them ensure their own safety.  The feel good rhetoric on the city's website is not enough; its not working.  

The final draft of Vision Zero needs to be something tangible, not rhetoric.  Otherwise, it seems people will continue to let themselves "be killed at alarming rates", such as walking into travel lanes.  Since it is the pedestrians and bikers who are the ones being "killed", why continue resisting pro-active safety measures that bikers and pedestrians can use to help themselves stay alive? 

To make a real difference, I would think in terms of a since and frank resolution that applies exclusively to the vulnerable.  There are all kinds of forums that apply specifically to consumers, as a self-help tool preventing them from being ripped-off.  It works for consumers, why not for pedestrians and bikers?
