Actually, it may not "educate" per se but it MIGHT HELP under certain
conditions; something Kimberly says below helps explain in a moment:

It's not commercially available. There ARE companies interested in
marketing it but the makers of the vest aren't yet sure they want to
market it given the time investment involved. They use it mostly as an
educational tool in their local cycling education efforts.

And there's where the vest might help with overtaking maneuvers; you
can see right away on approach EXACTLY how fast that cyclist is going
relative to you.
