is time in mapdist function real-time travel time or static?

Question

I am interested in driving distance and time using the mapdist function in ggmap.

Is this travel time timely updated (real-time traffic information) or

Answer 1

This function uses standard google API. There you can find that you would have to specify optional parameter departure_time to your request, to take traffic under consideration.

And if you look into mapdist source code you can see that departure_time is not part of your request (neither as parameter, or default option).
