That's the problem. I don't know if the message is important or not unless I see it. There wouldn't be a safety risk if at least the beginning of the message was displayed on screen. That would be enough to figure out if it's something worth stopping for or something that can wait.

Well it could be important. CarPlay has no problem displaying a notification of a message with a red dot or a popup from below. If it didn't, then I get it.

But it does show that there's a message but doesn't show the message itself: worst of both worlds.
