		+	Coming in very late, but physicist Randall is wrong. (At least, his mirror-engraver is wrong.) The objects in the mirror are not "bluer than they appear", because that statement implicitly privileges the ground's reference frame over the car's. The objects appear the way they appear, period. That's Einsteinian relativity's central lesson. If someone is on the same road, driving in the opposite direction, they see the objects as bluer than ''someone at rest with respect to the objects'', but neither of those reference frames is privileged over the mirror's.
