They do - there is a physical latch you can pull (at least in the Model Y) that opens the door even when the car is totally unpowered. I never actually knew about them, but I had passengers find them because people don't think of pushing a button to open a door. And when the latch is used, the car beeps at you and says something along the lines of "Your windows might be broken now when you do that".
