   Manufacturers have refused to change the standard order of letters on the typewriter keyboard even though some people who have never learned to type

   This is the principle in action, not a violation. Manufacturers keep the standard keyboard layout because typists have learned it deeply. Changing it would frustrate the very pattern users have ingrained. Maintaining the standard respects the principle.

   Government regulations require that crucial instruments in airplane cockpits be placed in exactly the same array

   Standardizing instrument placement across cockpits is the principle in action: pilots learn one arrangement deeply and can rely on it in any aircraft. This respects ingrained patterns, exactly what the principle recommends. It is not a violation.

   Automobile manufacturers generally design for all of their automobiles a square or oblong ignition key and a round

   This is also consistent with the principle. By giving ignition and luggage keys distinguishably different shapes, drivers can tell them apart by touch — a useful design choice for ingrained tactile habits. There is no reversal of an ingrained convention here.

   The only traffic signs that are triangular in shape are

   Reserving the triangular shape exclusively for "yield" signs sets up a clean and consistent visual cue that drivers come to recognize automatically. This establishes a useful ingrained pattern; it does not violate one. Nothing in this answer reverses or fights an existing convention.

   On some tape recorders the "start" button is red and the "stop"

   Why this is right

   This is the violation. Red is deeply associated with "stop" or "danger" — the partner of the stimulus's green-means-go example. Yellow, conversely, is associated with caution or "go cautiously." A tape recorder that uses red for "start" and yellow for "stop" reverses both conventions, fighting users' ingrained color associations. Pressing the red button to start something is exactly the kind of design the principle warns against — it leaves users prone to error and is therefore inefficient or dangerous.
