The autolock on the fire, to me, is proof that Elon fully intends this to be a working feature. He probably would want all of his cars like this so if anyone in one of his cars displeases him he can have the battery overheat into a blaze AND prevent the occupants from escaping.
If it’s on fire and the autolocks, you know the doors are strong enough to not budge when you try to kick them open.
