We have this in my town. Ambiguous zones. The idea is it creates confusion, and slows traffic. However, in my state, pedestrians have right of way on ALL roads. So the car simply slows. Mostly.

They did something similar in a big refurbishment of the town centre of the place I grew up in (in the UK). No road markings, roads and pavements both done with Belgian blocks, and just some big stone bollards to separate the pedestrians and traffic. Turns out drivers kept hitting the bollards so now they all have hi-vis reflective strips on them. Which definitely did not grant me much confidence in the driving skills of my town.

As a us citizen I can’t speak for everyone but I feel like the majority of drivers are responsible enough for it to work with only a few zooming BMWs

Meanwhile I’d probably hold up traffic because if I feel like I can’t make a decision with 100% certainty on the road I don’t execute, better safe than sorry

I may be over exaggerating a bit but mostly with stuff like unprotected left turn and matters that aren’t time sensitive and I have time to analyze I feel like if I have to ask myself “can I make this” and usually the answers no if I’m even asking

It has made me look like an idiot at some blinking yellows but it’s better than being t boned

Thank you for coming to my ramble

This suprised me when I read Killed by a Traffic Engineer. But in hindsight it makes sense. The road is not a regular, never-gone-wrong place despite our best effort to make it looks like one

I feel this would work in some areas in the US, i.e. smaller towns, possibly in the residential areas of larger cities. But in rush hour type areas? Hell no, it would be a massacre after people got used to these spaces.

Do you have more information about this? I would love to read more.
