Chariots are grouped as cavalry but also have the modifier frighten.

So maybe cavalry does frighten to an extent, and then chariots frighten even more with the modifier? Either way, I've added it to all cavalry (except horse archers, who infantry men would love to come to grips with).

Chariots frighten foot soldiers more than normal cavalry. That's how it's supposed to be.

The insane noise of the wheels / mass of the chariots themselves / devestation they cause in the ranks / sythed blades of the eastern variety / the fact that they aren't seen as often as normal cavalry to boot scares the ever-loving #$^& out of inexperienced foot soldiers.

With that bit of script edited as you have it, a crappy light cavalry unit could prance around the back end of an engaged unit of foot soldiers - even relatively experienced ones - and cause the unit to route without killing a man (a tactic chariots are useful for, one of the things that legitimizes their expense).

Elephants are also grouped as cavalry, and they scare folks too - is a guy on a horse equal to a guy on an elephant or a war machine? Methinks not.

Change it back!

edit: I could maybe see that trait added to cataphracts, but only because they had a reputation...even still
