Nas,

I have shot a few of these, mostly from the side - as our shadow followed along on the road and that was the intent to show the speed as well. This was the first time I thought to turn around and take it from behind...it was a bit hard to keep the camera level - so it is skewed and probably why you feel a little disoriented but I liked the effect and the way the shot turned out.

I am a lifelong migraine sufferer so I understand completely and I do hope you feel better.
