Can't keep up with this thread, but I wanna make a few comments on what's happening.
Tesla reducing the price by $2000 is most likely just keeping the cost of US Tesla sales in line with the cost of Europe and China Tesla sales because it is likely that the cost of shipping a Tesla to Europe and China is around $2000. Therefore, by lowering US prices by $2000, it expands their addressable market, create good will, and keeps cost in line.
Next, I want to take a moment to address Apple for a second before relating back to Tesla. Apple lowered their Q1 sales forecast and they blame it on China. But I think that's not the real reason. Apple is a classic case of the innovator's dilemma, where they are doing incremental improvements and increasing their profit margins. They can't or won't compete in the lower priced smartphone, and we see that from Apple abandoning the low priced iPhone 5c and SE. Instead, they retreated to even higher priced models (iPhone X/XS) to get even higher profit margins. This makes them very susceptible to being disrupted by low priced competitors because the low priced phones now finally have good enough performance for most.
Apple had the beautiful position of ~60% gross margins on their iPhones and a stunning ~90% of the smartphone industry's profit margins for years! Most smartphone makers actually lost money because Apple and Samsung had over 100% of the profits. What Apple did of increasing the average smartphone prices to get higher profits is likely a very poor strategic choice. This is because by raising all of their smartphone prices, and thus raising the industry average smartphone price, they allowed their struggling competitors to raise prices and bring themselves out of negative profit margins. That allowed Apple competitors to out-innovate Apple in various areas and slowly but acceleratingly eat away at Apple's sales. What Apple should have done is LOWER their iPhone prices. They still would have had a very healthy profit margin of say 40-50%, but it would have wiped out their competitors because Apple represent the ceiling of smartphone prices, and by lowering them, they lower average smartphone prices, and bring their competitors into further losses. This reduces competition and innovation from competitors, and likely would have been much better for Apple in the long run.
Now going back to Tesla. Tesla's decision to lower prices is, in my opinion, a fantastic strategic choice. By passing on savings to consumers as they improve production efficiency, they lower their prices, and make it THAT much harder for the competition that struggles to make a profitable EV. This has the strategic advantage of reducing the growth rate of competitors, which has side effects of reducing their innovation due to lowered profits that leads to lower R&D budgets. Tesla's continual price reduction is very smart to increase its EV moat against competitors, and the competition should be sweating bullets with Tesla's move of passing on savings.
