^^ This.
Both the SR and the SR+ were announced at the same time, yet mysteriously Tesla only applied for certification for the SR+, which it has. If Tesla ever had any intention of producing the SR, they would have certified it at the same time.
This is classic bait-and-switch, they used the last couple months to upsell SR folks into an SR+, and the few that held out are being given what is for all practicaly purposes an SR+ with a couple things deactivated, at a loss, just to get them off Tesla's back. As soon as all current SR orders are all delivered, the SR will be axed.
