I can’t help on the statistics for AUS or RHD.
I think most of us people in the USA use many things from the NEMA 5-15 (normal 120v mains wall outlet) cable that came with the car to HPWC ( High Powered Wall Chargers) with various different adapters and mobile connectors in between, including the Can Sr and Can Jr.
I mainly use an early 30-amp NEMA 14-50 mobile connector (home) or the Tesla J-1772 adapter cable that came with car (public). However, recognizing the early, dynamic situation that would obviously lead to today’s orphan status, I have redundant capabilities (Cans) as well.
