Its the humpback whale fin idea. The bumps don't help at 0 degrees, but don't add drag either because they are inline with the wind direction. But they make the humpback whale fin stall much less abruptly and at wider angles have a lot less drag ( and more lift).
look at this graph:
the peak and valley gets smoothed out
tldr: When the wind changes back and fourth over the stall angle (around 12 degrees in the example), it is much more controllable.
tldrtldr: The wheels handle better (if zipp got it right, no data yet...), and the idea should be put on 808s.
