Redundant, but superior to all comers.
Yeah the CCS connector is SO awkward, especially when you see anyone smaller/weaker trying to wield it and get it into the charge port - the combination of size, weight, having to align multiple oddly shaped parts of the plug and often heavy cables is a usability nightmare. That's after people have got the hatch and the smaller mini-cover thing open - ugh.
To me it looks like a design-by-committee job - I'm sure the CCS plug is 100% perfect on paper, but there was barely any thinking about non-technical requirements. The Tesla connector on the other hand was clearly made as easy and usable as possible AND technically excellent.
