Dimmer switches

Why were dimmer switches moved from the floorboard to the steering column?

I would guess they proved safer and/or more convenient and possible with the advent of reliable relays.

  1. Cheaper - Instead of a separate part, the switch is now part of a multifunction assembly.
  2. It was the popular thing to do to show that your car was more modern.
  3. It works better for one-legged people or those with a manual transmission.
  4. Specifically just to annoy you.
  5. Some other reason altogether.
