They've sold well over 100,000 cars. The current total is around 140,000. They project 80,000 or 90,000 this year, with a slow start, so I think their current rate is 100,000 if not higher.

Do their sales in the first 5 months of 2016 somehow not count?

I was looking at the wrong data. At any rate, the point is that Tesla is trying to ramp up production very fast. Going from 50,000 to 100,000 cars sounds difficult in 12 months, while maintaining quality.

Going from 2,700 to 22,000 in 12 months sounds difficult too, as does going from 22,000 to 32,000 and from 32,000 to 50,000.

Unless they have spent the past couple of years planning and preparing to up their capacity..
