But that wasn't what Tesla said.
It's a good thing I keep a record of all data sources I use. HERE is my data source. At 50:37 they said, "7% of the reservation holders are Tesla owners".
Transcript from 49:54: And it should be noted that these folks are not interested just only in Tesla Motors, but also Tesla Energy, because the price point of the Tesla Powerwall is an accessible price point for many of these folks and so they're expressing interest in both. In terms of S and X as a bridge to Model 3, we are talking through and thinking through that. Just as Elon mentioned earlier, the quickest path to receiving a Model 3 is being a Tesla owner. We've agreed that Tesla owners are receiving priority in terms of production, and so you can run the math I just mentioned. If 93% are new to Tesla, 7% of the reservation holders are Tesla owners. And the fastest way to get production vehicle even in 2017 is through Tesla ownership and so we're finding that there's a good conversion rate of folks that are coming in to test drive an S or an X who are Model 3 reservation-holders and are motivated to be Tesla owners now so that they can receive their Model 3 earlier.
By the way, this and other data sources I used can be found here on Data 1 tab, near the last columns.
