Like you, I found a lot of little things lacking. Weird things that despite how much other people tried to explain them away, still didn't make sense to me. My wife and I have now only driven performance german cars for the last 6 years now so our expectations were high.
Despite that, I still ordered a P100D.
It will be my daily driver and Autopilot is basically what sold me. Unlike you, I deal with a lot of traffic which is the bane of my existence.
