Popular Routes
The reason for this limit is due to the processing impact. Loading 500 routes at a time, when each one could have up to 50,000 points, would place such a burden on our server and network that it would adversely impact other users of the site. As per your other request to support plotting multiple layers with 500,000 points, you really need mapping software running locally on your computer for large scale mapping tasks such as this.

I would like to raise the 30-routes limit in a route collection, to a significant higher number, like 500 or more.
