Ongoing issue with mouse steering controls (Car left/Car Right) when a player is playing as the commander of a vehicle that has an AI as driver, this using the relatively recently implemented (Tanks DLC) commander vehicle steering).
Observed:
If you have Mouse Left/Mouse Right bound to both the Aim Left/Aim Right and the Car left/Car Right controls, then when as commander you move the mouse to look around in free-look or indeed to move the commander turret left or right, it will cause the vehicle (through the AI Driver) to steer in the direction of view.
Expected:
Moving the mouse left or right, when playing as a vehicle commander with an AI driver, should only rotate the players commander turret/weapon) or the free-look view. The vehicle should not turn left or right.
