There still seems to be a lingering belief that this had to do with an update.
I don't think that's right at all. An AWS server went down, meaning that our cars couldn't contact mothership. It would seem that that is enough to cripple them, because they go into some kind of loop or limp mode if they can't communicate with the servers.
That is appalling programming, and that is what needs to be fixed, and the lesson to be learned.
We, as users, also have a lesson to learn, which is that if these symptoms appear, we should simply switch off data.
It is a shame that the early, apparently wrong,diagnosis of a failed OTA is perseverating.
