Ann: 2019 Half Year Results Presentation, page-128

Settle down, Simon.
Its Friday arvo and beer o'clock.
I saw discussion of US fiscal years and didn't see the context of the graph. My bad.
btw: I agree about China

However, I remembered seeing this following info which is directly relevant to US tax incentives and the July-June state tax period.
"The Model 3’s June surge could be attributed at least partially in anticipation of Tesla’s tax credits dropping a second time as part of its phase-out on July 1 to $1,850"
