A man-sized object travelling at c or above would cause collateral damage. But nowhere near enough to hold Superman back as much as he does in the comics.
But taking character personality into consideration - Magneto wouldn't care. Superman would. That keeps Superman to his 90% speed of light and would not keep Magneto from opening up a black hole in the middle of Metropolis.
