Why were roman chariots raced on an oval track?

Roman chariots were raced on an oval track primarily to enhance the excitement and speed of the competition. The oval shape allowed for continuous racing without sharp turns, enabling chariots to maintain higher velocities and reducing the risk of collisions. Additionally, this design facilitated the use of a central starting point, where spectators could easily view the action from various angles. The oval track's layout also helped accommodate large crowds, making it a popular venue for public entertainment.
