In particular there is no manual door release for the backseat of a Model 3, and the Model Y manual door release is a cable hidden under a access door which is itself hidden under a mat in the rear door pocket [1] (assuming it has one, early model years do not).
A regular backseat passenger will never find the Model Y rear door manual release in the event of a crash without being shown exactly where it is. A regular backseat passenger in a Model 3 must either crawl into the front or break a window to escape.
I do believe the front door release is the same in all models though; which is a regular pull handle around where you would expect a normal door handle to be. Funnily enough, many people mistake it for the actual door release since the door UI is very unintuitive.
Edit: I know passenger, I just wanted to point out the absurdity of requiring intimate familiarity with a door to be able to open it, extending to drivers. Think car sharing pools etc, something the future will have more of.
Next up - in the next firmware update after fully self-driving, comes fully self-opening door!
