Besides, they all want to spraddle their legs apart and set their feet wide, so as to stand firm on the chariot bed, so they want the chariot body made as wide as possible.
"Now I don't need to plant my feet far apart when I drive.

I believe I could drive on one foot and keep my balance.

So I hold a broad chariot body is worse than unnecessary.

The lower the axle is set, the more sharply the pole slopes upward from the axle to the yoke-ring; the less of the team's energy goes into pulling the chariot along, the more of it is wasted, so to speak, on lifting the chariot into the air at every leap forward.

The higher the axle is set, the nearer the pole is to being level, the less power is wasted on that upward pull and the more is utilized on the forward pull and goes to produce speed.
"Then again, I maintain that the farther apart the wheels are set the more one drags against the other, not only at the turns, where anyone can see the outer wheel drag on the inner, but at every swerve of the team on the straightaway.
