I see automotive art as a visceral form of expression more than one form of art. You have color, form, motion, and sound. I'm not a fan of car shows but I love cruise night, but not for cruising I park on the route and get out the lawn chairs and watch the parade. Seeing the cars in motion, herring the engine, the exhaust note, smelling the rubber and unburned fuel, vewing the car do what it was built for.
One of my favorite videos is of Micky Thompson about 1969, the Mustang funny car just hits the chutes and for a brief moment lifts the car off the strip sideways then snaps it strait. There were pictures in the magazines of the day but they didn't do that ride justice, the motions the car made were beautiful and made an impression on a 12 year old kid in South Dakota.
Now that is art to me, automotive art.
