Had to be in Los Angeles Monday afternoon... decided to drive there in the morning from home in Saratoga, CA. Drove back that same night. Overall 745 miles in 18 hours. Only doable thanks to Supercharger network. 5 visits. Gilroy, Harris, Tejon, then on way home, an RV park for an hour on a N14-50, then Tejon and Harris SC's to home.
Car was great, and comfortable, for such a long extended drive. Got to learn lots about it during that time.
A few tidbits:
Napping while charging:
if you're stuck at a SuperCharger late at night with little open/interesting around you (I'm looking at you Tejon and Harris!), it turns out you can have quite a comfortable nap in your S. (Pulled into Tejon with just 9(!) miles range left on way home arter tooling around L.A. and climbing back up the grade going north).
Instead of reclining the driver's seat to nap, try instead leaving the driver's seat upright and fold your rear seats down flat, and climb in the back. You can quite comfortably sleep in the flat space now created from the trunk to the back seats. Made me want to put a little air mattress and pillow back there... it's actually quite spacious (I'm ~5'10"). Control your audio choices via iphone bluetooth, and quite comfy and functional. Given the amount of storage space you can still have while preserving the trunk and back seat for resting (Frunk plus floor of rear seats), you could actually do a bit of "RV-ing" in your S if you really were so inclined. (Sun shade and privacy shade of some sort for rear windows and hatch and pano roof would be nice additions).
