Recently my car length setting in cruise control changed. This was no doubt due to pilot error . However, when I looked at the autopilot settings, the ability to set the car length was no longer available. A timely you tube video told me how I could change it. My annoyance is that you have to be in cruise control AND be closely following another vehicle in order to use the scroll wheel to change it. In addition, half the time, the car thinks I am doing a command instead of the adjustment. Now, I really don't need to have such a fussy way to do this adjustment. The ability to do this in settings should be re-established.
