@Rycaut @inthehands I just dug into this myself and found an article that suggests the backup option for doing this from the outside is...a different way of charging the battery?
The article also implies a guy who got stuck inside one is stupid for not spotting a manual release that Tesla seems to have made an effort to conceal, so I find it telling they have to present this as an obvious solution. https://www.carscoops.com/2023/08/man-gets-trapped-in-hot-tesla-after-battery-dies-as-he-wasnt-aware-of-manual-release/
