Most of these are passive notifications -- i.e. they don't ping you they're just there in your notification bar (or if you swipe up to start the Google Now app).
In some cases, it makes sense for some of these to be notifications that ping you. I want my phone to remind me if I need to leave right now to make my next meeting.
Finally, you can configure each individual card provider to be on or off so if you don't like a particular type of card, just don't use it.
I'm excited to see if they will provide an API for this. I would love to write custom card providers so that I can get ambient notifications of things happening in my world (e.g. the build is broken on an OSS project I run, a motion sensor in my house was triggered, etc.)
