Actually, the human will have a similar type view as that of the ant, from
ground level. An example that points this out is in both real car racing and
in car racing sims, where one of the views you can switch to in playback, or
that they occasionally show on TV is the
camera-by-the-side-of-the-wheel-well-real-close-to-the-ground. Being closer
the the pavement makes the perception of scale different, and thus the speed
is perceived as faster. You also get this if you go go-karting. Though I
wouldn't recommend standing up in a moving go kart to see if your perception
changes :-)
