My touring bicycle has downtube shifters.  When I was riding it, I
would look down before shifting at the start of the ride.  After I
became accustomed to its position, I didn't need to look down.  If I
adjusted the saddle or handlebars position, I had to start over.  I
assume that racers and pros do not tinker with these adjustments prior
to a race and would therefore have the time needed to properly find
the down tube shifters.

In the my computer biz and piano pounding hobby, I've noticed that a
fair number of people look at their hands instead of the computer
screen or sheet music.  I had both of these problems when I was first
learning to type and play.  I've partly fix the keyboard problem and
can now type on the letter keys without looking at the keyboard.
However, the rows of numbers, function keys and number pad are a lost
cause.  I have to look at those.  The problem is that there are far
too many different keyboard layouts.  Recognizing the problem, I
purchase about 10 Dell SK-81xx mechanical keyboards for use at home
and in my former office.

I can now almost type with my eyes closed.

With the piano, the problem was that I play almost totally by ear.  No
sheet music.  Therefore, I had no incentive to learn to play by touch
or with my eyes closed.  I can play with my eyes closed on my Korg
DSS-1 synthesizer, but not on any other piano, organ, etc:

What's happening is that people have varying degrees of hand-eye
coordination.  Some people can type or play piano with their eye's
closed.  Here's an example of one pianist who can play without looking
at his hands:

For cycling, the trick is to reduce the number of variables to make
shifting easier for the rider.  That means don't move the saddle or
shifters, large paddle handles, and lots of practice.
