i would tend to think that power doors and power windows, on a car, are good examples of making a simple thing far more complicated and expensive than is necessary...and everyone accepts them as being a good idea
heck, electric starters on a motorcyle are another good example. i got rid of my electric starter and run my chopper kick start only. think about it. a kick starter is a simple level. kick it downwards and the bike starts. add an electric starter and you need a bigger battery, starter gears, a solenoid, extra wires of the heavy sort and the skinny sort, and a button on the handlebar....all so someone can push a button with their fingers instead of pushing a lever with their foot.
humans just love to find the most complicated way to do stuff. isn't that why we gave up carburators and points,( both easy to work on, dependable, and inexpensive to repair), and went to computer controlled fuel injection and electronic ignition( both of which are more complex to work on, less reliable [ think about how many times you end up replacing various sensors ], require special tools and equipment, and far more expensive to repair) ?
