Even when it works its awful. The 2nd row is short on room. The 3rd row is tiny. And you cannot fold the 2nd row seats so even if you fold the 3rd row down you can't fit a bike in it.
Here is a video showing how much more hauling space there is in a small LEAF than in a Model X.
And you can't even put stuff on the roof of the Model X due to the stupid doors.
Get an AWD Model S. Skip the stupid Model X.
