The current AP, with no camera/radar at eye level, can drive you under a semi-trailer during a momentary lapse of attention. I can't trust a system that only "sees" a few feet off the ground. I know I'm not suppose to trust it, and to pay attention at all times, but the peace of mind that is lost with the lack of another camera/radar at eye level is significant to me. For this reason, AP2.0 for me is not an incremental change but a huge change. I had an AP loaner for a week and I did a lot of highway driving with it, but I just couldn't get my mind past the fact that there's nothing looking out for me at eye level or higher. So I couldn't relax and let myself enjoy it. It really depends on the individual as to whether 2.0 is incremental or significant, and one's ability to put trust in the current capabilities of the hardware. The accident involving the fatality spoke volumes to me. The new hardware will not allow for that type of accident, regardless of the driver's inattentiveness.
I know this is summons and not AP, but it does go to show the limitations of the current hardware:
