I think, OP, that if you spent some time in IFR training you would soon learn to appreciate the standard layout of the "big 6" instruments.
In cars, every maker has a different idea of what constitutes the best ergonomics. It changes with the whims of the day. And you don't actually have to have any of the instruments to safely drive your car.
Your survival in IMC depends on the instruments and your ability to process the information they provide. Imagine learning IFR flying in one aircraft, then switching to another the next day. Disaster looms.
