Some Egyptians think their massive spoilers help with handling their chariot but they just introduce drag for no real benefit because the power comes from the horses in front of the chariots and allowing your chariot to slide to the side as your horse pulls it through a tight corner makes it easier for the horse to maintain speed (or horses if you're a fucking show off).
You know how many snapped hitches I've seen on chariots with spoilers vs how many without? 3 and 1, which should show a clear trend. And that one without a spoiler happened because she was trying to go way too fast over cobblestones for some reason.
For some reason.
