@LouisIngenthron I do have a bunch of links to news articles of "no charges filed in fatal accident", though I suspect that many of them are (to some degree) the correct call for the situation. But they serve to illustrate that "vehicular manslaughter" is not the panacea you suggest. Cars are still the chosen priority.
