Looking at the rear wheel of a Porsche Taycan Turbo S in the Norwegian arctic

Looking at the rear wheel of a Porsche Taycan Turbo S in the Norwegian arctic.
The start and end is especially interesting as it is there you can see a good demonstration of the rear-wheel steering (default on Turbo S) option working.
Thoughts? Is the rear-wheel steering more or less pronounced then you thought? Have you seen it do its thing before?
