There's no manual release on my model 3 for the rear passenger doors. Only front doors have it.
Depending on the configuration of the car, if you end up in the back seat with the door closed and the child lock is set on all rear doors, it can be pretty difficult to get out.
Kind of related, Teslas (some?) don't have a manual hood release either, so firefighters' first hope is to find the guy who knows what menu on the fucking touch-screen is going to pop the hood. E.g., when making sure that the high voltage stuff can be disabled, the car won't try to leave with fire crews in the way, and so on. There are more... destructive ways to get in, and it will happen, but they could have just installed a pull cable like everyone else.
