No, we have had much later departures than that in the past.
Up until the last quarter Tesla operated on a business model that attempted to deliver every car made in that quarter.
It was a very successful model that made quaterly balance sheets a joy for Wall St and ensured good cash flow. It had disadvantages too - it was very hard on Tesla employees who globally had an end-of-quarter rush and the cost of sale was higher on the basis of 'no expense spared' to achieve deliveries by quarter end. (Tesla had very specific hard dates for shippers to achieve and so ended up paying top-dollar rates for ship charters)
At the end of last quarter, domestic sales in China slumped (probably because of the pandemic) but despite Tesla incentives (free charging etc) the market was swamped and so production was shifted to EU models. This caused sensational financial headlines "Tesla sitting on 71,000 unsold cars" which prompted demands from institutional investors for Tesla to take positive action, which lead to price cuts, which increased demand (which actually hadn't gone away but was just suppressed by the pandemic in China). Anyway, there is now huge demand in China (and a few broken windows at Tesla showrooms from very disgruntled buyers who lost out from the significant price cut!)
The move to straddle the quarter-end was always going to be painful but it should be a once-only affair as long as you don't return to the "quarterly" model again. Despite the whopping price cut, China remains 'easy money' for Tesla and is the market to concentrate on if Tesla wish to send a message to Wall St short sellers who have done (too) well over the last year.
I watch with interest to see how Tesla play Q1 23.
