"Inadament" is not a standard English word; it might be a misspelling or a misinterpretation. If you meant "inanimate," it refers to objects or things that are not alive and do not exhibit life or movement, such as rocks, water, or furniture. If you meant something else, please provide more context for clarification.
Snowmen are inadament objects.
It really depend on what your about to hit ... If its a person your about to hit brake and brake hard you don't wont to swerve (steer) out the way because you might hit something or someone else ... If your going to hit something that's inadament then steer out the way ... Now, if your about to hit a animal then you don't brake or steer out the way you keep going the animal will move out the way and if it doesn't you just hit it ... Braking or steering out the way can and will get you into more trouble then just hitting the animal; the animal will probably do more damage to your car then the car did to the animal...
