OK, obviously, you did see them, for they are not truly invisible, and even if their ninja outfits absorb all light, you would still notice a stygian person-shaped void pedaling a spectral bicycle silhouette in front of you.

A more serious question: Suppose someone throws a couple of those black milk crates in the road and leaves them there, or a Herman Miller Aeron Chair in Sit-for-Less True Black. Are you telling me that you are powerless to avoid colliding with these objects if they're in your way? If so, I might suggest that you're overdriving your headlights or maybe following the next vehicle too closely, something like that. Yeah? Or no?
