“manslaughter”: def. The unjustifiable, inexcusable, and intentional killing of a human being without deliberation, premeditation, and malice.
Using your example, if someone steps out in front of your car, intentionally, and you strike and kill them with your car, is their intent imputed to you so that you are guilty of manslaughter?
This isn’t a story about American tree-huggers/`Lisa Simpsons’/trust fund babies lying down in front of logging trucks. Actions have consequences. She would be alive if she had not placed herself in front a working bulldozer. The operator was just trying to do his job.
Has nothing to do with tree huggers or the like. It's a legal issue. When you stop being blinded by your political beliefs, you can see the true meaning of the laws.
You example is not sufficient enough to make a determination. Could you have stopped or not? That is the critical issue. You don't have a free pass to run over evertyone who steps in front of your car. If you did, the cities of the US would be strewn with bodies everyday or until people get the point.
Let's proceed under the assumption that we are both rational thinking people. So don't insult me again with this type of example and comments.
