Mostly we drive on two lane roads. If others are ahead, and behind, I just maintain a safe distance from the car in front, and hope those behind will do the same. If nobody is around, I always use CC because otherwise I will invariably end up speeding, with no audio cues...at least none an old guy can hear.I strongly disagree with this. One of the challenges I have in the Bolt is that it's difficult to know what speed you're going without glancing at the speedometer. There's no engine noise that changes pitch with speed, so I find myself having to pay closer attention to the speedometer than in any of my other cars. Looking at the speedometer means not paying as much attention to the road ahead. If I could set the cruise control to 30km/h then it would remove the distraction of having to check the speedo as much.
