In charged.hk we are working with government on issues like charging infrastructure, FRT EV exemption and more. Feel free to join - memberships start at "free" (associate), while normal memberships are 200 HKD / year. We are totally non-profit, charitable status, just a bunch of us trying to make life easier for EV owners in HK.
Estates are a hard and stubborn mass to work with, and eventually it might need legislation to force the rest of them to allow chargers installed. The electric companies need to catch up also, though, as there must be enough power. It would suit HK very well if installing solar panels was worth while, but an almost endless amount of paperwork and permissions are standing in the way. And there is no net metering or other feed-in compensation in HK.
Anyway, congratulations to your Model S, whether delivered or still in the queue!
Btw, we have groups on Whatsapp, LINE and FB in case you like to join ...
