Is there a theoretical reason why they are supposed to be "better"? I
did try Googling when one of the blasted things arrived near here, but
couldn't find a good explanation.

Yes, to look at the red/green men, you have to face the oncoming
traffic. Supposedly you are therefore less likely to run across the road
having failed to notice that there *is* and oncoming traffic (regardless
of the state of the men).

One of the many flaws is that if you are consciously wanting to look for
the red/green men, you probably also aren't likely to be taking a punt
on running across the road regardless of the state of the lights.

And are the sort of people who if the green man changes back to red as
they step out will step back and wait for the next green man. Now they
don't see it change back.
