> Vision Zero is based on an underlying ethical principle that "it can never be ethically acceptable that people are killed or seriously injured when moving within the road transport system." In most road transport systems, road users bear complete responsibility for safety. Vision Zero changes this relationship by emphasizing that responsibility is shared by transportation system designers and road users.
Using Los Angeles as an example:
https://ladotlivablestreets.org/programs/vision-zero
https://laist.com/news/transportation/2020-traffic-deaths-lo... for the graphic "Traffic violence in Los Angeles" showing the increase since Vision Zero was adopted.
Then you have enforcement issues like jaywalking laws, the wording and culture around collisions and referring to them as "accidents", etc.
The entire country was REbuilt (US cities were not always like this) around the car. Until that changes, no city will reach Vision Zero.
