Adaptive Cruise Control problems of the 2026 Subaru Outback

I'm new to this automotive technology. When I was introduced to the car, one of the "features" indicated was the ability to sense and slow down for curves, if the system sensed the need, when operating under the cruise control option. In testing my different options of my new car, I was using the cruise control on a 65 mph road in TX set to 60 mph. As I entered the curve the car did not slow down. This was a surprise to me. I contacted a Subaru dealer about this. I was told that my trim level did not have this "option". Before I contacted the dealer I did look in the Subaru eyesight drivers assist technology owners manual. On pages 280 and 281 of this manual in the cruise control, pre-curve speed control*, on/off. The *note is "if equipped". My car is not equipped. I was not informed or cautioned about this when I went through the delivery process. I did not know I did not have this feature. My complaint is this. If the car is equipped to assist steering when in cruise control, for safety, all models should come standard with the pre-curve speed control. It only takes one instant for a new driver to loose control if expecting this feature to be present. I am an experienced driver. I was able to take corrective action to avoid trouble. But, I did anticipate the car to slow and was startled when it did not.
