- Until you start shipping, you are burning money. Hit 0 and you die. Tesla is widely believed to need another round before it starts shipping Model 3, even if everything goes to plan. [1]
- US tax rebates for electric vehicles are phased out after a manufacturer has sold 200 000 of them. [2] The longer Tesla takes to start selling Model 3, the more it will have sold of the upmarket (hence less rebate-sensitive) S and X, the fewer price-sensitive Model 3s it will be able to sell at the rebated price.
- Competitors are not standing still. Who knows what else will be available in 2019 or 2020? And how long will those 400k preorders stand in the face of delays when there are alternatives?
