A NASA website shows the accurate data. Generalizing the vectors showing the drift, we get a picture like this (please compare with the proper measurements):
This is quite in harmony with the opposite rotation of North America. The radius of rotation is considerably larger, as the Eurasian Continent spans 150° along the 51st parallel, but North America spans over only 60° at the same latitude.
This provides a base to analyze the tectonic drift further. Scientists can pinpoint the rotation points etc.
