I understand it's probably needed for US due to longer distances, but for Europe LFP would be a better compromise IMO.
9 years? Tesla was founded in 2003 and released the Model S in 2012.
[edit]
about 15 years to get to the monthly volume that the A4, 6, and 8 are manufactured.
The Model S was announced in 2012 as their first "mass produced" road car (and they don't appear to have broken 100K cars in a year until ~2017), so that's 15 years to get anywhere near the scale of a grown-up car manufacturer.
To reiterate, they didn't have to support other production in any of that time, and they didn't have to make any sort of profit during any of that time.
To compare, Audi spits out ~2m cars a year, and can't just stop selling cars to retool their factories.
Also, Tesla's growth is not an overnight story.
I would love to have an Audi that looks like one, feels like one and drives like one, but electric. I looked at what they have now and there's no sense in purchasing it because it gets 30% less mileage on full charge than a Tesla. So technology-wise, where it really actually matters, they are way behind. No doubts they will catch up, but they will need time.
