Martial Arts and Chariots

[Polydamas]

Hello All, a few MA related questions for a Chariot Archery style I'm working on.

Per p. B548, turning in an exposed seat/saddle to fire at foe behind gives a -4 penalty to hit. What if you are standing in a cramped vehicle and can actually turn around? Maybe -2?

What penalties are there for driving a vehicle (chariot) without using your hands? With one hand? How do they relate to the drive-while-shooting penalty of -2 or the weapon's Bulk? Would a No-Hands Charioteering technique be reasonable for people who can drive with the reins tied around their waists and their hands full of a bow and arrow like pharaohs in Egyptian art? (I expect this was as much a way of showing the pharaoh as heroic as a real technique, but it should be cool for PCs whose driver just took two cubits of reed arrow to the throat). If so, what would a reasonable skill penalty be?

Lastly, how do these two techniques look? One should be familiar from Low Tech (3e).

Sharp Turn (Hard)

Default: Teamster
Prerequisite: Teamster (any); cannot exceed prerequisite skill + 4

If you know this technique above default level, you may use it instead of the underlying skill whenever you make a control roll to turn earlier or tighter than is normally allowed; see Pushing the Envelope p. B395 for details.

Trample the Slain (Hard)

Default: Teamster
Prerequisite: Teamster (any); cannot exceed prerequisite skill + 4

You are trained to leap a chariot over simple obstacles, such as logs or dead bodies. If you know this technique above default level, you may use it instead of the underlying skill whenever you make a skill roll to pass over a simple linear obstacle. This technique does not help against anything which cannot be bumped over, such as pits, brush, or a field of stakes.
