Given that Tesla has opened the door to paid DLC (speed boost for 2K), I would suggest giving SR+ owners the option to pay to upgrade to Premium interior. Some of us could not afford the LR versions but would be perfectly willing to pay 1K or 2K to have the full sound capabilities and real time traffic navigation.
I understand that it would be ideal if OTAs remained free, but in this case I see a win-win situation for SR+ owners and Tesla's bottomline. Let us pay and get the upgrade through OTA.
Had already suggested this in a call to Ride the Lightning (podcast).
