From the press release (at: http://ir.tesla.com/news-releases/news-release-details/tesla-q1-2019-vehicle-production-deliveries http://ir.tesla.com/news-releases/news-release-details/tesla...): "We count a produced but undelivered vehicle to be in transit if the related customer has placed an order or paid the full purchase price for such vehicle." It sounds like it is count as sold, but not delivered. Production was 77100 which leaves about 3500 cars as both unsold and undelivered. That is only about half a week of production, but at the same time it implies softness in overall demand compared to the past.
