Because Tesla’s build quality is very poor. Instead of fixing that problem they have decided to focus on producing more cars.
People can go from mega hype-person to mega detractor quite fast.
Those sentiments trail any actual improvements for a long time.
The cars from their newer factories have generally better quality.
And even so, when looking at QC report Telsa might not be great, but its not really an order magnitude off to anybody else either.
So to suggest they should stop growing to fix QC is just delusional and literally nobody, not even you as CEO would do so.
