Can FME help to export traffic layer of Google map?

Legally? Most likely not. And knowing Google they've also locked it down technically.

I found something similar in this thread:

But really curious about the reply of geosander: Basically used an HTML page with custom CSS styling for the Google Traffic Layer and background map, so I would get a "high-contrast" traffic map without too much background noise. I ran this HTML page on localhost and then wrote a script (outside FME) that would render this page at a certain pixel size. The resulting image basically was like a map tile. You needed to specify the latlon bounds and level of detail for the script and it would generate all map tiles for that area within a couple of minutes. The tiles were processed in FME and the traffic congestion values (green - orange - red etc.) were assigned to actual vector road segments along with a timestamp. Along with some average hourly traffic intensity data we had, we could give a rough estimate of the amount of cars that were actually passing by on a road segment at a certain time.

But im a newbie so it would be great if anyone can explain these in more detailed level.
