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.

I am a geologist, graduated from the University of Iceland, and taught geology for a few years. I have gained some knowledge about Earth's inner structure, so I provide this website as my contribution to answer one of the greatest questions remaining within the realm of geoscience. Experiments show that the mantle should form convection rolls when close to the melting point. I took this literally, and calculated the dimensions and shape of these mantle convection rolls. Then I compare that model with the surface. This makes it possible to provide many interesting examples about geology found on my blog.
