Have had my 60 for a month now and LOVE IT!
Have used most of the Super Charging stations. So amazing. Can't wait for more. The California ones are nicely spaced out from SF to LA and allow a nice buffer of 30-50 miles range upon arrival to the next station. Barstow to Vegas was ok, arriving with 33 miles in Vegas (you can thank the mostly downhill grades on the last 40-50 miles for making it work).
Just wanted to warn owners with a 60 regarding the driving leg from Vegas to Barstow: it could be a CLOSE CALL! I was max charged on the Strip at 211 (Venetian was best bet- The Strip is a tough place to try and charge). Car had 4 people with average luggage. Had air on low entire time. Very windy. Never more than 70mph. Some slow spots of traffic, which helped range. The climbs were tough over the mountains, watching mile range drop about every 15 seconds. The last 50 miles to the super charging station was filled with range anxiety. I was cringing in my seat, and wouldn't go over 55mph, even in the truck lane. The truck lane is not a place where a Tesla belongs. Pulled up to SC station with 4 miles! Way too close of a call!!! Another Tesla had just pulled up when I got there. He had an 85 and just came from the Strip as well. He had 42 miles left!!
So use caution on this leg. It proves that a Super Charging station is needed at the Primm state line (Jean, NV). Elon, or Tesla techs... if you are reading this, please consider a charging station at Primm.
Best of luck owners. See you out there in this fabulous car!
