Technically, drag *is* friction I included "streamlining" in my
list of fixes to reduce friction. Another phrase that means
aerodynamic drag is "air friction".

Very good point. Air friction gets much worse as you go faster, while
other types of friction only get a little bit worse. So there's a good
reason to pay special attention to aerodynamic drag.
