I don't think that was the point they were making. They were saying that, here in the UK, if the light is green for you as a pedestrian, there is a guarantee - legally enforceable - that traffic cannot cross your path. Unlike in, say, many other European cities and - ime - ny city.

Worst thing for pedestrians and cyclist is "turn right on red" rule.

If you want to turn right (in right handed flow) you can enter intersection on red (in Poland when additional green right arrow is lit up) but you have to yield to everybody, also pedestrians (that have green at the time).

In theory you are required to stop before you enter on red but most drivers don't and some don't even slow down more than is physically required to make a turn.

So if a cyclist or a pedestrian appears in path of such car unexpectedly (because there might be high vehicle waiting for green on the next lane) it is a dangerous situation.

Right on green is pretty brutal as well. A cyclist is going to keep moving forward and completely depends on the visibility of the drivers turn signal, assuming they decide to use it.

Been around in other cities for as long as I remember. The nearest junction to where I grew up in Glasgow in the 80's allowed crossing in all directions at one time.

Only European country I know about that has pedestrians on green crossing cars is Germany.

And I live in Europe.

Also France.

And Italy!
