I agree that the San Diego Supercharger is terrible. It's also far from a freeway exit/entrance. I've only been there once on a weekend, and that area was a ghost town.
I think the Superchargers I like tend to have some things in common:
* It should have plenty of stalls, and it shouldn't be too crowded -- let's face it, nothing is worse than getting to the Supercharger to find that they're all taken, and that you'll need to wait.
* It should have walkable amenities.
* Food and/or Shopping.
1 point each for safety, night access, walkability, restrooms, restaurants, wifi, stall availability, shopping, other attractions.
and 1 point because it's a Supercharger.
Here are the ones I've visited so far (all in California)
Mountain View: This one is located at the Computer History Museum. I've only been here at night, and it was raining so I didn't get to step out. I'm familiar with the area, but the problem here seems to be local charging and high Tesla density. Even at midnight in the pouring rain, there were probably 8 or 9 vehicles there. They have lots of chargers. I only did a short range charge here. 7/10.
Gilroy: Outlet Mall. Lots of chargers here, and also some other EV charging types. There's also an In-N-Out here too. Good walkability. Good shopping. Just wished that they had more food choices. Had to do a longer charge here. 8/10
Buellton: Santa Ynez Marriott. I usually only need to do a short charge here, but The Marriott is pleasant. They have wifi, and a bar/restaurant. I wish there was more to do within walking distance. 7/10
Atascadero: At Rabobank. Usually after driving down from Gilroy, I'm ready for a break. I always plan on taking a short charge here, but I always end up taking longer charging than I thought. Walk and explore the area --
Oxnard: located in a outdoor mall. Plenty of places to eat and shop at. Not sure what it's like when the mall is closed. 7/10
Culver City: At Westfield. There's the mall, but when it's closed, there's not too much around. I stopped here just to check it out and gauge stall availability. Lots of chargers here, and lots of cars charging. Probably one of the bigger Superchargers I've seen. 7/10.
Redondo Beach: Hilton Garden Inn. I like this Supercharger location a lot -- as previously mentioned, their bathrooms are nice, there's wifi, and a lounge, and a bar and restaurant. It's walkable to an In-N-Out too. (by the time I get to In-N-Out, order, and then eat, I usually get the charge is nearing completion message). Stalls are often crowded, but never full. 8/10
Hawthorne: Tesla/SpaceX. Lots of Chargers, not easy to find, and you need to snake through a (sometimes security guarded) road. There's no restaurants or or shopping nearby, however. It's neat to go there once just to see, but this one is one that I often skip. 6/10
Fountain Valley: At Petsmart/Costco Plaza. I really want to like this Supercharger, but I just can't. This Supercharger takes some of the pressure off of SJC, but it's also heavily used by locals -- in one sense, it's a good location because there's some stuff that's walkable, there's food, restrooms. But there's two additional hazards here: shopping carts and Costco shoppers. Skip it for travel charging unless you absolutely need it, because the LA superchargers are usually less crowded. 6/10
San Juan Capistrano: I'm really not a fan, and fortunate enough that I don't often need to stop at this location. There's lots to eat and see here. The problems are always congested stalls, which results in needing to wait to charge. I'm also not sure where the bathrooms are if the restaurants are closed. 5/10.
San Diego: Qualcomm. I don't like this location because there's nothing really to do here while waiting to charge. 6/10
