Picked up my grey/black/19" Model S 60kwh last Wednesday at the factory and drove it directly to its new home in LA. The drive was no problem even though I used standard (not max/range) charge, and took the beautiful, hilly, and windy scenic route detour: US-101 to CA-198 to I-5.
Hope this log is helpful for current S-60 owners and anyone considering a 60!:
Left Tesla factory at 1:40pm with not-quite-full standard charge of 185 rated miles.
Arrived at Gilroy supercharger via US-101 (42 miles driven) with 150 rated miles remaining, and topped off for 10 minutes to full standard charge of 190 rated miles.
Arrived at Harris Ranch supercharger via US-101 and CA-198 (146 extremely hilly miles driven) with 31 rated miles remaining. Charged for exactly 1 hour (check out the gift shop at the Harris Ranch restaurant in the neighboring lot), and left with 186 standard charge rated miles (got impatient so didn't wait to full 190). Note there is as of now only 1 supercharger at this location.
Arrived at Tejon Ranch supercharger (116 miles driven) with 36 rated miles remaining, and charged for 33 minutes to 141 standard charge rated miles.
Arrived to my destination in LA (86 miles driven) with 46 rated miles remaining!
Total trip time: 7 hours and 35 minutes (note there were no other cars at any of the superchargers during my trip)
I drove an average of at least 5 miles over posted speed limit the entire way, after Gilroy. I had climate control set to "range mode" but temperatures were moderate so this probably didn't make much difference.
If you are considering a Model S -- get it! Definitely the best car I've ever owned, and the superchargers work great.
In California there is also an extensive network of level 2 EV chargers (see the Recargo, PlugShare, and Blink mobile apps) that add 20-25 rated miles per hour of charging, which in most cases is perfectly fine. The 60 seems to be suited for most uses, including road trips. This past weekend I took it to Palm Springs, where I re-charged overnight at the Hilton, with no problems at all.
