You're completely guessing, though. If you try to work out a reasonable gross margin based the financials from the previous quarters and current ASP/option mix, it's easy to get to a higher number than 15-16%.
Yes, I'm only guessing of course - but how would such a calculation look like? Maybe we can establish rough error bars and probabilities.
@luvb2b laid out the basis of his 16% estimate in this comment:
"agree it's an open question, and some of it depends on where you start your q2 estimate. but my gross margin walk would go like this:
4.5% q2 gross margin + 4.5% pickup from depreciation math + 1% from higher asp/mix + 6% efficiency gains = 16%
the 4.5% from depreciation math was outlined further back in this thread. efficiency gains in the past have been much better than 6% per quarter, but of course i would expect less efficiency gains over time. last quarter (18q1 to 18q2) i would rough out the efficiency gains in the range of 10-15%."

I.e. he already included the positive factors you mentioned. Also note that there's some uncertainty about whether 4.5% was truly the q2 Model 3 gross margin. If we go into the Q2 report:
- $3,357m total automotive revenue and $2,666m cost of revenue: a gross margin of 20.58%, rounded up as "21%" in the report.
- If 18,449 Model 3's were sold with an ASP of ~$55.8k then that generated a Model 3 revenue of $1,029m. (Note that Tesla did not break out Model 3 revenue.) $2,328m revenue for S+X.
- If Q2 Model S+X gross margin was 28% like in 2017, then cost of S+X revenue was $1,676m, and this leads to Model 3 cost of revenue as $990m.
- $990/$1,029m = 3.8% gross margin for Model 3.
