Tesla raised prices in order to reduce the time between order and delivery when customer demand got too hot. Raising prices also improved profit margins during a time of rapid capital spending. Now customer demand has cooled with the international economic slowdown, and lowering prices increases the time between order and delivery as more customers are enticed to order.
Also to add, Elon/Tesla is 100% transparent about pricing strategies, and it's exactly this. Other manufacturers obscure this behind dealership models, Tesla does it out in the open.
Does anybody sell more than 2 million >$70,000 vehicles a year? Tesla wants to sell 2 million cars this year and 3 million next year. The total market size for premium vehicles is only so big.
