To put that in perspective a different way the 10,000 a week goal is more than the top selling US car sells per week. It only takes ~4,200 a week produced for US consumption to get on the top 20 US vehicles list, and ~7,500 a week allocated to the US to be the top selling car (that's car not vehicle, it would still be behind one SUV and 3 pickup trucks at that level).
Here is the top 5 from last months US sales
- Ford F - Series PU 68,243 (best selling vehicle)
- Chevrolet Silverado PU 42,282
- Nissan Rogue 38,119 (best selling SUV for Feb 2018, Toyota RAV4 outsold it for 2017)
- Dodge Ram PU 33,299
- Toyota Camry 30,865 (best selling Sedan)
So if they can top 4,200 a week before shipping any overseas they'll be popping up on best seller lists (top 20 overall, top 10 sedan).
If they can top 6,000 a week before shipping any overseas they'll be in the top 10 overall and top 5 sedan.
The quote below is that list extended to about top 20 length:
