Could it be that there are many documents containing both taxicab and
distance that have nothing to do with the "taxicab distance"? Searching
with quotes around the search term google advertises 

about 936 results for "taxicab distance"
6930 for "rectilinear distance"
38200 for "manhattan distance"

Whether you like a term and agree with its (alleged) bias or if it's in
common use are two different questions.

I think Robert addressed the latter while your answer implied the former.
