Interesting! I did not know that Tesla was still using volunteers to help with peak delivery times! Good for you! Since I live in Dedham, maybe I should do that as well....I had the pleasure of volunteering to help in June on several quarter-end delivery days. Goal was 60 cars into customer hands per day. Cars would come in from the offsite logistics lot and onto the supercharger to charge up to 80%+ for delivery. Add to this owners swinging through to do routine charging and... superchargers full all day long. Even if the 8 V2's were explicitly closed for public use they would still be overutilized during peak delivery periods. Tesla needs more supercharging for deliveries, preferably V3's without V2 stall pairing/load sharing. Doing overnight pre-charging of cars being delivered the next day would also help, although the charge and deliver cadence actually worked quite well overall.
And as a coincidence, today I stumbled across what is apparently the off-site logistics lot. I have known where at least two previous locations were, and this is the furthest away their remote lot has been, so far as I know. (But I claim no special knowledge, just random accidental discoveries.) I wonder if the used cars are there, as well?
