This has now started to annoy me a bit too. The amount of times I glance down and think I've got a notification, only to find that it's telling me the weather outside the window I'm sitting next to.
The "travel to" is sometimes interesting, since it seems to pick up routines, but my life is pretty boring, so I've never had cause to use it. That, plus it updates slowly, so it'll tell me I'm 10 minutes from home when I'm inside.
I don't mind them being there if I scrolled down to view - similar to how Google Now works on a handset, but to have them constantly reappearing kind of dilutes the concept of notifications.
I'm not sure I entirely buy their concept of notifications-only on the watch in the first place. Some of these cards represent information that I may want to know on demand. Delivering them only in the manner of a notification means that I can't find the information out right "now" when I want to. And, it means that they unnecessarily alert me to information that I don't want to know at that particular time.
And, if I want to leave them visible (i.e. not swipe to dismiss them), then they continually clutter the bottom of the screen as if they are important information that I'm not aware of - even if I've already visited them and read what they had to say.
There needs to be a concept of "information available" which are screens that can be set to "always available" and they do not act like notifications - they never vibrate and they don't show up on the screen, but you can swipe down to them when you wish.
Even notifications need an "acknowledged, but not dismissed" state so that even if it was a text message or phone call that you missed, you can leave it on the watch but once you've read it you can have it not peek out at you when all you want to do is read the time.
The data provided on the watch needs a lot more flavors and distinctions than "everything is an equally important and annoying notification that you must deal with or dismiss or it won't go away".
