While shooting a vineyard for a client in Sonoma County I was high up on the top of my photo van when I heard this beautiful, out of place noise. I turned to see this roadster flying along the road. I had my Nikon in hand with a manual focus tilt / shift lens. I quickly focused and the tilt and shift was at full as I panned. This was the result. Cool!

Quite original! Like the blur effect.
Thank you! Done in camera not post production.
