I hear ya... For me the only item on that list I would really care about is AutoSteer+ if it does a much safer / better job...
Automatic lane change could be very cool, will see the reviews to know if it's more than a nice to have. I imagine it's not weaving in and out of tight traffic at 70mph.
My garage / driveway is straight, not sure how much help smart summon would be, but would need to know how capable this feature is, maybe it could do a lot more. I don't image it'll be allowed to leaving a store parking space and pick me up out front.
On Ramp to off ramp navigation is really only saving you a minute or so from when you otherwise need to take over anyway...
From what I've read self parking is slower than just doing it yourself, but that could be better now as well...
Can't wait for the reviews to start coming out (hopefully end of Dec)...
