The new law permits pedestrians to cross a roadway at any point, including outside of a crosswalk. It also allows for crossing against traffic signals and specifically states that doing so is no longer a violation of the city’s administrative code. But the new law also warns that pedestrians crossing outside of a crosswalk do not have the right of way and that they should yield to other traffic that has the right of way.
At least in North America, around 80% of the population lives in a populated area. That means even if we only eliminate cars for urban areas, that’s still most of the cars removed. The only way I see people in rural areas getting around without a car would be with electric cargo bikes and robust train routes.
