[Q] "Am I Late For Work?" Google Now command

not sure if its already implemented or someone has already made it, but would there be a way of adding a google now command like "am i late for work?" or "am i going to be late for my doctors appointment?"

Using the command would search your calendar for what time you start work or have an appointment, then use google maps to find out how long it is going to take you to get there from your current position before determining if you're going to be late or not.

What do you think?

just seen a flaw in this as your phone wont know which mode of transport you're using.
You could add "in a car" or "on foot" to the end of your question.
