To be fair, if the car is offline while a newly installed app logs in, then the app won’t be able to locate the car until the car checks in. Which is not actually the end of the world, and there are ways to mitigate this. (See iMessage and Keybase for a couple of different approaches to this. See Signal for a shockingly poor group of bizarrely mutually incompatible solutions that barely work. I think that Matrix tries, too. MLS should be able to handle it, and piggybacking off an existing standard like MLS might be entirely reasonable albeit dramatically more complex than the simple solution I outlined.)

Well the reasons I can think of are either things like the server being broken, which can happen without any encryption, or she didn't finish setting up her app and waiting for it to sync which can also happen without encryption. Or she was removed from the list because she didn't open the app for a year... which can also happen without encryption.
