I use the Gilroy chargers fairly often and I've never seen any reserved signs on any of them. As markb1 mentioned, the four to the right of the power junction are the original ones. Although they say 90kW, I believe that all are now 120kW chargers. At any rate, the Gilroy chargers seem especially prone to charge rates that vary wildly. I've had the rate vary from 7kW at one charger to almost 120 at another. This seems to go beyond the typical variables of outside temperature or the number of charge ports in use. As far as the original question, I think that the "reserved" sign is probably "reserved for Tesla owners". Go ahead and use them. If you have any problems with the chargers, just call the help number. I was amazed that the guy I talked to knew when I got there, what stall I was in, the color of my MS, and much more. These folks seem to be on top of everything!
