Imagine 16 to 20 cars flowing in formation down a three or four lane closed stretch of highway. Now and then half or all of them exchange lanes, building a new pattern. Every other lane slows down while the others speed up. Or four cars in the middle seem to build a rotating circle as they alternately speed up while moving to the right, slow down to the right, slow to the left and speed to the left.

The thoroughly choreographed and practiced road ballet of color-coordinated cars could be filmed by helicopter and accompanied by Motown hits. As the sun goes down, the swinging convoy would waltz towards the blazing clouds with organized use of head, tail, brake and directional lights.
