For those wondering about DMV processing times for the title, I took delivery of my 2021 Model 3 SR+ on 12/31/2020. Tesla Colma delivery center didn't receive the DMV documents back until 1/4/2021 (due to New Years and weekend, so FedEx overnight took longer). The title date was 1/15/2021, post mark was 1/28, and I received it today. Still a fairly long wait, but not as bad as some accounts I read.
Still don't have the license plate or permanent registration card yet though, but I guess I can start on the CVRP application, now given I have the final license plate number now (didn't do it before because people mentioned if application was processed before ownership transferred in DMV sometimes application gets rejected).
