I don't think space is 4D. In the current 3 dimensions we are free to choose the absolute orientation of a coordinate system, as long as we end up with 3 orthogonal axes. If space were 4D we would be able to reorient 4 coordinate axes just as we please, which as near as I can tell, we can't. Time is clearly different. That's also why we have a different name for it.
