Sure. This does show that they're having serious delivery logistics problems, which we knew.
(Not enough parking lots on the East Coast.)
I still don't think it's a coincidence that:
(1) The AWD cars which "missed the train" sold out within a couple of hours, while there were still a lot of RWDs to sell
(2) People ordering RWD -- unrelated to this event -- have been getting their cars in as little as two weeks and no more than four weeks (with the exception of one poor guy whose order seems to be lost), while people ordering AWD have been told "um, we'll get to you when we can" and given estimates of several months
(3) there was a leak sometime back that they had much more demand for AWD than expected
(4) there was a leak that they had a bottleneck in front motor production
I don't think Tesla can produce 100% AWD cars at the maxmium rate of the factory yet. If they could, they would vastly increase the AWD/RWD ratio.
