Not everybody is ready to live life on the knife's edge.
I tried to talk my wife into getting rid of the minivan & keeping the Leaf when the 3 comes, but she doesn't want to be stuck with a car with limited range. We're probably just going to keep 3 vehicles. That way, she can use the Leaf for short trips, and have the minivan available for longer trips (the 3 is mine ).
During the Q1 Earning call on May3rd, Elon was saying production late 2019, probably 2020. In this week's Shareholders meeting, Elon seemed slightly more optimistic about "hitting the road in 2019". There's a lot of moving parts to getting there, so I'm sure ANY estimate at this point is uncertain- new factory, new platform, new manufacturing techniques....
I do find it interesting though that of all the upcoming vehicles, the ONLY one we don't have an approximate unveiling date for is the Model Y. Presumably it will be before the Pickup in "18-24 months" that Elon said back in May. But again, considering they have to build/convert a new Fremont-style plant for the Model Y, I don't think they're being cagy, I think they're going to have to wait and see. But I wouldn't be surprised if along with the Gigafactory announcements later this year we don't get Elon revealing where the Model Y will be built.
