I played CE again today and realized you just tap X to perform actions like opening doors and entering/exiting vehicles. This can sometimes get in the way of things, like if you try to reload in a vehicle you will jump out instead and trying to reload by a button or something will activate the button or you'll get in the vehicle.
I think they should make it like Halo 2 and 3 and stuff where you hold the X button down to perform an action. What do you think?
