Retroreflectivity is different than just reflectivity. While most objects are reflective to some extent or other, they tend to scatter the light in all directions. Mirrors reflect the light to the...uh...you know how mirrors reflect light. Retroreflective materials reflect light *only* in the direction of the source (plus a few degrees around the axis). Even mirrors don't do that. |
