This close-up of the New York chariot shows the holes, which secured the strands of the floor mat, all along the D-bar.According to Bela Sandor, professor emeritus of engineering physics at University of Wisconsin at Madison, the bow-and-arrow construction of the D-frame and pole provide spring action and shock absorption during acceleration and deceleration."There is no evidence of chariot racing from that era, but these chariots have many technical features that imply a pedigree based on racing," Sandor said.
