I just stopped by Mtn View SpC to supercharge after going on a mountain bike ride down south, and man is it packed already! And that's on a Sat afternoon, I'd hate to see weekdays... Only one non-handicapped spot left when I arrived so I had to share and was capped at 200A, though my SoC was under 30%. Eventually moved and got over 300A. But then someone else parked next to me so it dropped again. New cables are cool though, didn't feel that flimsy at all. I took a photo of the cable with a quarter for reference.
I personally think Tesla screwed up on the location of this SpC. They should have built it off I-280 by 85 or 84, away from densely-populated areas. Then it would truly be a "long-distance travel" SpC, which is what Tesla says their purpose is, and wouldn't be as hogged by locals as Shoreline. Half the cars were full of people waiting in their cars anyway, so it's not like they're coming to visit the computer history museum or something. Color me unimpressed...
