Is Google Now a useful utility for others? I recently activated it when I purchased a new phone and am having a hard time understanding how to use it. It's showing estimates for how long it will take me to get home or to work but they are always based on locations where I was a while ago and often outright ridiculous, e.g. 2 hours 30 mins to go from Alcatraz to my home, by bicycle? The other "cards" seem to show up randomly, like the stock quotes that are always up top when I want to see the weather and hidden when I want to see stock quotes. How do others make use of Google Now?
edit for clarification: I have set it up to prefer cycling, but Alcatraz is an island.
