it was covered in Elon's original comments.
He's still saying feature complete by the end of the year, but you will still have to monitor. Then sometime in 2020 work to remove that monitoring. Then sometime after that work with regulatory agencies so that there doesn't need to be a driver at all in the car.
He even addressed the whole 1 million robotaxi thing that spun inaccurately by the media. Basically that they will have 1 million Tesla vehicles on the road that are hardware capable of being a robotaxi if you pay for the FSD upgrade. Not that they will necessarily all be working as a robotaxi in 2020.
What other questions did you need answered?
Oh yes, my bad. I was referring to the questions but Elon covered it in his presentation.
