This is not "surprising", it is natural:

Born rigid motion is the natural way a solid object accelerates, as long as it is pushed or pulled from a single point, and the acceleration is small enough that the inter-molecular bonds of the object remain on average unstressed (i.e. the object does not break or deform). Those bonds will try to keep the inter-molecular spacings constant, making this as rigid as possible for an atomic object, and that's just what Born rigid motion is.
