I'm amazed that the car stayed on the ground. Both Stanley and Doble made steam cars that had more power than the suspension could handle. A speed record attempt:

"As the Steamer started its run, it was silent except for a low, soft whistle. This rose to a faint whine, and a jetlike white stream flowed from the tail of the car. Soon the head of the driver could hardly be seen in the blur of speed. The car passed the 100 m.p.h. mark and surged up to 197 m.p.h. As it was about to touch 200 m.p.h., however, the racer hit a slight bump on the beach. The light car took off like a wingless glider, soared for about 100 feet at a height of 10 feet, then crashed to the cement-hard sand in an explosion of steam and flames. The driver was flung clear, badly injured but not dead."[1]
