Why does the resume button exist at all? I am surprised that someone could not come up with this on their own: because it is more convenient than bringing the car back up to speed, getting it where you wanted it, then hitting the "CC" button again. Hit the brakes, then press the button and let the car bring it back to speed. It's not life changing, but a nice convenience feature. And it's been in cars for at the least the 50 years that I've been paying attention, probably longer. The button that always mystified me was the "cruise control ON/OFF" button. Hit the ON button, but you still have to set the cruise control. Umm, why isn't it just ON all the time? Some cars had it, some didn't. I have never come to a reasonable UX/engineering reason for this.
