We entered a turn rated at 25 MPH with adaptive cruse set at 45. As we proceeded deep into the turn the adaptive cruise responded to the conditions and lowered our speed to 25 MPH. We tested this out on several more turns rated at 35MPH and 25MPH respectively and without out fail the adaptive cruise responded with a reduction in speed as we reached the depth of the curve.

The dotted yellow line in the above image reflects the portion of the curve where adaptive cruise decreased speed in response to the curve.
