We want to give the player more time to strategise. Hopefully you won't notice it but we've segmented the game up so at one point, you'll be focused on shooting at a vehicle from range and won't be too concerned about your driving. At other times, you'll have to concentrate more on your driving style.

This lets you strafe left and right but you can't move forward and backwards. It's based on the action from films like Heat. You don't see people running around and shooting all over the place. It's a more measured approach, where you find cover, fire, and then move onto the next piece of cover.
