At the D unveil, Elon talked about the P85D having a performance setting of "insane", in addition to normal and sport. That was the first time I heard of any kind of a setting that affects performance other then steering, and there doesn't seem to be any info out there on this yet, other than a tweet from a Motor Trend staffed with what may or may not be an actual screenshot (and it only shows two settings). Jonny Lieberman on Twitter: Has anyone heard any more on this, for example about what the setting actually affects in terms of performance? Does it limit acceleration, or maybe just make it less jarring for day to day driving? I'm curious because I'm on the fence between the 85D and P85D, and one of the concerns is that the acceleration on the P is just too much to handle for people not used to performance cars (my wife, others who might drive it occasionally). A setting that tames the car's responsiveness would alleviate this concern, leaving me with no reason to not get the P85D, other than cost, now that it can be had with the 19" wheels.
