问题
I have an application that requires having many (sometimes over 50) dynamic routes added to the google map. Using the DirectionsService, I am able to add right around 10 routes or so before the requests start to fail with the status of "Over Query Limit". I was wondering if anyone has encountered this situation and has found a way to deal with it. It seems that even if I pause between requests, I am still failing for anything over the first 10. Not sure if there is a request limit for a single map instance?
Any help with this would be much appreciated!

According to the documentation, you can only get up to 2 requests per second. If your code do that slower than 2 per second, that should be fine.
I used the setInterval(function(){.... to test it and yup, if you do it slow enough it seems to work.
