What if there's someone in the car?

Don't leave a person in the car.

I mean, I tell myself not to lock my keys in my car, but it has happened on occasion. Do you think you'd be able to escape your car if locked in? I feel like I may be able to kick my way out or otherwise break a window, but I'm not completely sure of that.

You use the headrest for that.

Vehicle headrests are deliberately detachable so the metal prongs can be used to break the window.

I'm skeptical, but that may be the case in Europe. It does not seem to be in the US https://www.snopes.com/fact-check/car-headrests-emergency-es...
