In case you thought cars would become safer as technology developed… rest assured, Tesla is finding newer and ever-dumber ways to make their cars dangerous to occupants (and others).
TL;DR: If you’re in a Tesla and it loses power (like in a fire), the only way to open the doors is often an unlabeled wire behind either two panels or a speaker grill. Tesla owners are DIYing janky rip cords to make that wire easier to pull to escape.
Before cordless sawzall’s became a thing, every fire depadtment/rescue squad would make up a handle that you could attach a used sawzall blade to for cutting safety glass windshields. And they still carry them to this day as a backup. They are amazingly effective. You just need a hole to get started.
These days, every rescue/fire truck carries a cordless sawzall as the go to for such jobs. No special blade required.
