The Arma 2 steering on vehicles is a lot harder and honestly more annoying due to the fact that it doesnt auto correct to the centre after you have steered. In this, you have made it more realistic by having to turn the wheel and then turn it back. It does auto correct but only after a slightly too long period of time.
It would be nice to have that back to how it used to be, as right now using the mouse to steer is near impossible.
