I wasn't implying that shutter speed would have an effect on the rolling shutter distortion, what I was saying is that just like we can use shutter speed to give the appearance of a frozen in time subject, the faster the electronic shutter clears the distortion can be unnoticeable.

You mentioned 1/500th of a second, 1/60th and 180th of second. Do we know how fast the electronic shutter actually loads and clears the sensor?

I do not think a true global electronic shutter would be possible, but one so fast that there is no noticeable distortion in the image would be. When one that fast arrives it would be called a global shutter.
