No I wasn't, that's NP trying to move the goal posts of the discussion.
I was countering his assertion that fly-by-wire throttles and electronic
controlled gear boxes are used because they are cheaper than the older
mechanical systems.

Both the electronics and software control are vastly more expensive to
develop and have higher per unit costs than simple throttle cables, or a
mechanical gear linkages.

The reason they are used are to increase fuel economy, reduce emissions,
and to give the easier driving experience you expect of a modern car.

Most people would find a 30+ year old car without all these electronic
aids very difficult to drive, without the ECU compensating for engine
temperatures, atmospheric conditions, fuel quality and load.

Find someone old enough to remember having to use the choke on a cold
morning!
