Elon: Yes, we have basically the LA to San Francisco pack swap capability in place. And I believe all Model S owners in California area have been invited at this point to try it out. And what we’re seeing is just a very low take rate for this fast conversation. So, we did an initial round of invitations. We did like 200 invitations. And I think there were a total of four or five people that wanted to do that and they all did it just once. So okay, it’s clearly not very popular. And then it was like, we’ll actually expand that invitation to old customers but I would expect that initial sample group is that all customers roughly behave like that initial sample group is just people don’t care about pack swap. The Superchargers are fast enough that if you do the driving from LA to San Francisco and you start a trip at 9 am, by the time you get to say noon, you want to stop and you want to stretch legs, hit the restroom, grab by to eat, grab a coffee and go on your way. But that time, the car is charged and ready to go and it’s free. So it’s like why would you do the pack swap. It doesn’t make much sense. And we’ve booked pack swap into the car because we weren’t sure if people would want to choose the pack swap or not. We thought people would prefer super Supercharging with low interest. So that’s why we booked the pack swap capability.
