I don't think this works without all the other bits of dutch traffic planning like separating infrastructure very strictly for the most part, slowing down cars a lot wherever that isn't feasible or wanted and also that basically everyone still also rides a bicycle instead of using a car exclusively. Approaches in isolation such as this are tried every few years here in germany - which is less carbrained than the US as per infrastructure at least - and it usually fails horribly because the underlying mindset of the country is still "road = cars, get out of the fucking way". It very occasionally works out in very small, rural communities where the socetial pressure not to run your actual, known neighbour over takes hold but otherwise it's a mess.

I once went out of my way on a cycle trip to ride through Bohmte, which has tried a rathe more dutch shared space approach with no traffic signs, no lights, no sidewalks in their inner city and it does not work one fucking bit, it works out to be the worlds most stroad. Mind you, the clearly designated sidewalk is a later addition on account of how much it did not work.
