I don’t know why I was being so dense on this. Was thinking it’s still July right now!
So, yes, I got approved on 8/15, so have until 9/14 to sign the loan. Then from what others have said can schedule the funds transfer anytime within the next 30 days. Thus, if you want, you could delay funding the loan for up to 60 days following approval.
If I get a call from Tesla anytime soon, I’ll just get the funds on the spot. If by 9/14 I still haven’t heard from Tesla, I’ll just sign the loan and get the funds right then, in case Tesla calls me at some point and says your car is ready now (one can dream).
