To refuse to have the Breathalyzer test.
Changing the name of this, I agree with you, makes it more serious. It doesn't change the consequences. You've still killed somebody.
But being convicted of a homicide, do you think it might be more likely that the person will refuse to have the Breathalyzer, on the same grounds that over the years people who were picked up did refuse because they'd rather be convicted of failing to have a Breathalyzer test than to be convicted of impaired driving?
That was the incentive, and might they have more of an incentive now? It's just a thought.
