Comment on All Maps in China are Transformed

It could simply be a map projection issue - where the traffic data projection is slightly off by an order of 1000 meters. This datum shift could be easily fixed by Google.

A map projection issue would show up in other places on the map, and would have been fixed by now.

Not true at all. Data can be pulled from multiple database sources, each with their own projection info., so if there are datum shifting issues, you can have some pieces not aligning to basemap while others do.
