What is the definition of a deadly weapon other than a firearm?

The court instructed the jury with CALCRIM No. 875, which stated among other things: "A deadly weapon other than a firearm is any object, instrument, or weapon that is inherently deadly or one that is used in such a way that it is capable of causing and likely to cause death or great bodily injury." Defendant contends the court erred by instructing that a weapon could be either inherently deadly or deadly in the way it is used because a car is not an "inherently deadly" weapon. "We review defendant's claims of instructional error de novo." (People v. Johnson (2009) 180 Cal.App.4th 702, 707.)
