> the left side spoke operates the adaptive cruise control system, and mistakenly brushing against the "resume" button could re-engage cruise control to whatever speed it was last set, causing the car to accelerate Why does the resume button exist at all? In my 2018 Toyota if you break while having cc on then cc is disabled, end of story. And if I turn it back on it's set to my current speed. It's not adaptive though. But still, if you break it should be gone. No coming back to the previous hidden state.

I use resume all the time - the first example that comes to mind is that cruise control won’t stop at a red light (obviously), so I’ll brake to a stop, then all I need to do is start taking off again and hit resume. No need to think.

  I guess that's very convenient. What if you needed to also press the gas pedal after resuming it to bring the car back to the set speed? Would that be too much trouble? You'd get benefit of deciding how fast you get back up to speed.

    Most cruise control systems let you do this already. I know I can accelerate harder than the system does by itself and it’ll just let me do it, then drop back to its usual program once I stop. I wouldn’t like it if I had to consciously stop at the intended speed though, that defeats the entire purpose.

In my 1984 Honda, the resume button brings me back to the speed I was set at before I hit the brakes.

  "Resume" has been a feature of cruise control since the dawn of electronic memory. The Motorola MC14460 integrated circuit and the even older and hilariously complicated Zemco CompuCruise had resume features.

What model? My '98 Sienna had resume functionality that I used all the time, so I'd be interested to know when and why they removed it. I find it most useful for highway driving to resume my preferred speed after passing a slowdown.

    Looked into it a bit, and I don't see anything that indicates the Auris has a different control scheme than the standard. It looks like it does actually come with a resume function which can be used after breaking: > Pulling the lever toward you cancels the constant speed control. The speed setting is also canceled when the brake pedal is depressed. > Pushing the lever up resumes the constant speed control. However, resuming is available when the vehicle speed is more than approximately 40 km/h (25 mph).

      Thanks. Although I really was safer not knowing that. However "resuming is available when the vehicle speed is more than approximately 40 km/h" seems like a probably sufficient safeguard.

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.

  I don't think that car should be accelerating for any reason other than pressing a gas pedal. Definitely not after the driver manually presses the break. Maybe the on/off button (I have it as well) is just additional safeguard against accidentally enabling super dangerous feature, which is defetead completely if it doesn't turn off on breaking and can be resumed.
