They're building cars, so it's more like ATX 24pin style cables, but this is generally true. Cables, wires, ropes type of objects are like cardboard thin robots with hundred joints in series and under someone else's control, so it's hard for robots to deal with. If you think about it, people hate cables too. We easily get tangled in headphone cables when they're wired, and we fail to coil or untangle Ethernet cables properly all the time. EV charger style of short, thick cables should not be THAT hard, though. The more likely problem here is that they just can't handle the task of securing and inserting the head of the cable against resistance.
