Jeff, great to hear about your new owner experience as I too explore my evolved transportation system. I feel so much the same about most everything you said. Although, I have noticed no extra looks in my direction; Palos Verdes is swarming with Teslas...but it's nice to know mine's better than every other one I see (I've yet to see another refreshed S and unless you really know what to look for, it blends in to the old S crowd).
While I'm an instant fan of TACC, I was a bit disappointed how leisurely it gets back up to speed when the slow/stopped traffic starts moving again (even on follow 1) but that went away when I found I can goose the "throttle" to catch up and TACC stays engaged. Learning something new everyday...
