Like I said, his estimation transfer function clips at 2 years.
What goal are you attributing the 2020 date to?
Elon said in the podcast (10:45) it will be feature complete this year. 2020 is the guess at when you can sleep all the way to your destination.
Huh? He literally changed his vow in under 30 days. He said they would be 99.9999..% and have safe FSD this year to all his investors. Then a month later he says it will happen end of 2020. Seriously?
2/19: end of 2020
1/19: end of 2019
11/18: end of 2019
3/17: mid-2019
6/16: before mid-2018
1/16: early 2018
12/15: end of 2017
You actually gonna defend that? Elon could come out tomorrow and say he's building a time machine, its easy and he will have it done in 2 years and you will find a way to defend him. I'm done here.
