Most people don't know that the headrest (head restraint) can also be used to break a window in several ways. I'd known about this for a while, typically there's just a simple mechanical button you have to depress to remove the headrest to be able to use it in this fashion. Then, for ergonomic reasons, I went to change the headrest orientation one day (I know this is stupid) - and, it turned out, in addition to a mechanical push button to remove, I also had to shove a tiny ass pin punch deep into a hole in a really weird place to fully remove the headrest. This was in a Lincoln, and I'd never seen something as stupid as it in any other car. So much for the idea in the back of my head Id've been able to rely on it if I'd ever needed to break a window. Even more of a reason to just buy the purpose made breaker/cutter, never know what unconventional BS some brands/models may be doing. edit: sorry, speaking in general - Tesla's dont/sports cars tend to not have detachable headrests. Or maybe most newer cars don't in general, haven't looked into it much.
