First of all, yes - I do believe that we should normalize knowing how to operate the safety systems in the cras we drive. It's crazy to me that's even controversial. I do actually read the manuals for all the cars I own.
But second, I think there is some confusion here. For the driver and front passenger, there is a clearly visible manual release on the door in the model X. It's so prominent, most inexperienced users and guests believe it is the primary release The pull behind the speaker grill is the manual release for the rear seats.
