> I remember something about the manual door latch being behind a speaker like cover in early Tesla models?
Was curious and did some searching, AFAICT it looks like someone on the front-seat is often OK, but if you're in the back seat you may be in trouble.
Model S involves a cable behind your ankles:

The Model X involves removing a speaker grille and pulling a cable down and towards the front of the car:

In the Model 3 you have to know to pry up a piece of molding in a lower pocket of the door before manipulating a cable:

Model Y is like 3 except some of them do not have a manual release for rear-passengers, and those that do involve another step to pull up a mat from the bottom of the door-pocket:
