Actually, it's an example of when it's wise to sacrifice intuitiveness for an economic benefit. I don't see any reason to believe that "virtual" systems are somehow exempt and there is obviously a cost in making something "intuitive". The answer to your second question is a first-year calculus problem: Voltage=acceleration to some limit, which you can plot as angles over time across time and speed. It might be fun to work a protractor and some graph paper to see how it would differ with more than three settings.
