Especially egregious considering it's likely kids will be back there. And the release is in a place thats probably impossible to get to from the front seat (in the model Y)
I had to kick the rear door of the family car after an accident when I was about 11. The car blocking both doors on the other side was on fire, and I was later told our car was also on fire.
I wouldn't have known to lift the carpet and pull some release tag, and with the door badly damaged from a collision I also wouldn't have been able to kick it while pulling the tab. It was night, so finding and using a glass-smashing tool also seems unlikely.
You probably can't break the glass either. Newer vehicles, especially Teslas, often have laminated glass that glass breakers have been found to not break.
