Say 'drivers', not 'cars': it's the people in inside the boxes that do the stuff

The way we refer to people interacting on roads has to be impersonal or it would be too sad to bear. The language, a defense mechanism to avoid massive cultural guilt at the damage and carnage we allow for the convenience and speed of some. If we spoke directly about the numbers killed and maimed across the world pointing out the people responsible,we'd be pointing to our friends, our sons and daughters, ourselves. So we point to the cars instead and make these inanimate objects responsible.
