metric in brain?

[Vasavada, Kashyap V]

Jo, Cathy, Siegfried and others,

If human brain has some kind of distance/time metric, then why are estimates of distance and time more often wrong than right. I have brought up this several times. Human estimates of height or distance of a tall building or a TV tower behind a small house, size of a full moon near horizon etc. are routinely wrong. This is why instruments are important in science and engineering.
