The only part of AP that I have any use for is the adaptive cruise control. It's rather frustrating to have to buy additional features that are of limited value, when everything is software configured. Collision avoidance is standard, so we know the required hardware is in operation. Why not an option for just TACC? I'd pay a grand for it. We will be doing almost all of our driving in moderately heavy urban traffic and all the rest of the AP capabilities are not needed.
