Imo this is a good time to do the update. The world economy is weak with high interest rates needed to fix inflation hangover from printing money during covid. Also the war in Ukraine costing a lot while with high energy and food prices while the market adapts. Add to that a big heat wave and rain storms in many parts of the world leading to draughts and floods. Meanwhile the Chinese economy is suffering from covid lockdowns hangover, American boycotts, their insane property bubble slowly popping and mass youth unemployment. For Tesla their 4680 ramp has been delayed and they are in the switch from HW3 to HW4.
So this seems like a good time to do the line upgrades and refresh models. Sure it will cost a lot in a difficult time. But better that than to halt production when demand is sky high when the economy is booming in another year...
