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.

For a couple of generations we've been trained, cajoled and exhorted to
look for the red/green men across the road, high up. We simply don't
expect to find them on our side of the road, at knee height. Sideways.
