I'd be surprised if the bikes rode with their blinkies on. I never ride without front and rear strobes, when solo. But on a group ride, I only had to be yelled at once to "turn the damn thing off" because it annoyed and was too bright for those behind. The last rider in a group should have a strobe, but not the others.
In any case, a terribly tragic affair.
