teslas have frameless windows in the doors, like subarus and some bmws. like bmws but unlike subarus, the windows automatically retract a bit when you open the door.

this is because while subaru windows just push in against a gasket on the body, tesla and bmw windows also push up into a recess in the gasket. this removes a lot more wind noise.

the difference is that bmws have a mechanical door handle with a sensor that lowers the window, while teslas have a button to open the door and drop the window, as well as a separate emergency release latch that's purely mechanical and does not affect the window. meaning that if you pull the manual release and push hard on the door, the window gets stuck in the gasket and shatters. this can also happen in bmws but only if the 12V battery is flat.

to add insult to injury, the "open door" button on at least the model 3 is where the window controls would usually be, and the manual release is where a door handle usually is.

Edit:

like so:

IIRC, that is internal internal (inside the door frame), not just inside the car internal
