Plus, I live in an apartment block with the under-building garage not having any plug sockets. Unless I drape an extension lead down 5 storeys and about 150m away, I can't see the upgrade path at the moment. There probably are sockets closer, but it's not as simple as "park and charge", but either "lobby the building management and get sockets installed" or "find a hacky solution with long cables".
