Look at the last one with the path. It's super obvious. (You can look at the prior pictures to see where the lines on the concrete are.)
Rest assured humans do not drive this way; you can take my word for it.
Just as a another reference point, the car's left wheels went comfortably over this line on the left turn (see how the wheel is turned hard to the left); should make it clear enough that this is abnormal. I actually don't think a car could have squeezed by even if it wanted to. But this has been reported many times. It's also not new behavior I don't think.
Virtually every human will drive to the concrete, staying right of the imaginary lane line, slow to around 5mph, check for cross traffic, then initiate the turn. There's just not really any other way to do it.

As another reference point, you can just see where the "normal driving" Google car was relative to mine, again observing joints on the concrete:
