It's a bit like the way the electron gun paints an image on a CRT Television or Monitor onle in reverse.

The trouble is that things that are moving fast in the same direction of the scan can "avoid" being scanned by "dodging" the position of the scan on the sensor.

Look at digital pictures people take from moving vehicles and you'll see wierd artifacts of this effect. Telephone poles will look like they are curved or sometimes the whole image will look squished thinner horizontally. It depends on the way a particular sensor scans what the results can look like.

Rotating objects present really big challenges for these sensors because the object is changing directions. In this case a spoke got warped into oblivion while the others got "bent". In some of the other images the spokes look fatter on one side of the wheel than the other (no two the same thickness).

It's pretty normal to see stuff like this.
Smarty-pants! J/K. I was wondering about the wheels too, thanks for explaination.
