Google Now is broken. I get to work, and there is a "time to home" card, and vice-versa. It also thinks that I would like to go to work in the middle of the night on a weekend. It keeps showing me directions to places I've never been to or never searched for. Or, I arrive somewhere and it immediately shows me a card for "time to home". Even though I have a calendar entry that has a location (so it knows I'm where I'm supposed to be) and it knows how long I'm supposed to be there. There's also all sort of other idiocies. For instance I only got google now recently and then I traveled back to my home country for a couple of days. And what google now did was bombard me (hundreds literally) with cards for directions to every bloody address I've ever searched for in that country (months or even years ago). Wtf? I really appreciate the complexity of a system like now, but as it is it would be better if they turned it off. It is broken.
