First of all, you literally used the word "fault"...so seems like you do care about blame.
But to the main point, the OP used the word "SHOULD"...as in, it is an aspirational thing. So you seem to be arguing that you don't believe it should be the case that our roads are safe enough that distracted (or perhaps, for example, blind, pedestrians, or child pedestrians) can be safe on those streets, rather than that they aren't that now.

As for whether there are places like that in the US...sure, there are some, like Disney Land, and Mackinaw Island, and other resorts. But in actual cities, in actual neighbourhoods where people actually live...basically none. Maybe parts of Montreal...
