At anything more than a yard or two, the optical sensors won't pick up anything except retro-reflective tape unless they are PERFECTLY perpendicular to it. Last year, before we got the retroreflective tape, we played with the optical sensors and a small hand mirror. It took me several minutes to line up the mirror properly so that the sensor would "see" it, and as soon as someone so much as bumped the table, it lost it.
Finally, the diamond plating in front of the operators station starts a full 17' from your robot. The max range on the sensors is approx. 20-25', and that's with the retro-reflective tape. Simple mirrors is a whole lot less, meaning there's a good probability that they can't even see far enough for this to become an issue.
