Ah.
Now I understand the issue.
Yes, last year, it went down slightly but not much. It was some 16.5-17 M vehicles sold in America, last year.

My point is NOT that Tesla will hit 9m sold in 2-4 years.  They do not have manufacturing capacity for that. My point is that total sales is going to plummet below 10M, possible as low as 7-5M. Of that, Tesla will dominate demand.

Consider trucks. Right now F150 is top dog. But Tesla will in 2-3 years produce a truck that has the torque of top of F250, and only cost around $35-40k. And for under 60k, u get Autopilot, 300 MPC, better interior, likely a tool chest in the frunck, ability to run 120V/10A outlet. With that, do u really think that F*50 stand a chance? I don't.
