I call that "mental masturbation for engineers" (I are one). We do things because we can, not because we should. I complained about this for the first years of the DC Metro's decision to introduce fare cards and reading machines that would compute fares on the basis of time of day and distance, rather than a simple card/token for one size fits all. The software finally caught up with the hardware after only a few years.Germanic marques tend to take an engineering mindset to menu structure, iow it makes sense to the designers but not so much the end user. My Audi and wife's Benz are similarly non-intuitive. Just one of the things I accept (and I'm an engineer; but admit I've been guilty of same in my younger designer years).
