The chariots themselves were modified war chariots, essentially wooden carts with two wheels and an open back, although chariots were by this time no longer used in battle. The charioteer's feet were held in place, but the cart rested on the axle, so the ride was bumpy. The most exciting part of the chariot race, at least for the spectators, was the turns at the ends of the hippodrome. These turns were very dangerous and often deadly. If a chariot had not already been knocked over by an opponent before the turn, it might be overturned or crushed (along with the horses and driver) by the other chariots as they went around the post. Deliberately running into an opponent to cause him to crash was technically illegal, but nothing could be done about it (at Patroclus' funeral games, Antilochus in fact causes Menelaus to crash in this way,) and crashes were likely to happen by accident anyway.
