They're now making in the territory of 5000 cars a week, almost double in 2 months. Regardless of how you interpret it as burst week or not, the production rate has ramped up significantly.
We are now seeing the goalpost being moved from whether Tesla can achieve this goal, to Tesla being lax with quality. Perhaps we'll hear soon 10K/week is unattainable. I guess that means they are making progress.
