I wonder if there's any issue with disorienting pilots - having lights sliding along the ground could provide misleading visual cues. I know the flashing lights on tall objects are sync'd specifically to avoid any illusion of movement. Probably more of an issue in the US where there are a lot of low-currency private pilots flying night VFR.
