This does happen - the blue glow from a reactor is due to particles traveling faster than light in water (n=1.33). The limit is only c=speed of light vacuum

Does energy have to obey the light speed limit? In any solid object, the "push" is a pressure wave, and propagates from one end to the other at the speed of sound for that object's material.
