Re: FCS is not new.
I'd also argue that I've had my brake vacuum assist "turn off" in may car (due to another small vacuum hose splitting at the end and starting to leak badly), and let me tell you the only reason I didn't full on crash into the vehicle in front of me when it happened was that I tend to drive hella cautiously. I defo did skip a beat though seeing as how the effect can best be described as "step on the brakes and nothing whatsoever happens" even though technically they do still work, you just have to apply roughly 10Gs worth of your body weight on them to do what they did before. So I'm sorry, no, modern "luxuries" in a car are NOT, in fact, luxuries.
