I don't suppose others share this opinion, but it's not unique to me.
I think there should be no such offence as dangerous driving causing death, and dangerous driving causing bodily harm. The crime lies in the dangerous driving -- subjecting the public to undue risk of harm.
The fact that you did actually harm a member of the public changes the outcome (obviously) but it doesn't change the crime. Whether I do or don't kill a child makes not the slightest difference to the degree of my negligent and dangerous behaviour, nor to my mental state that led to it, nor to my actual performance of it.
The difference between dangerous driving, and dangerous driving causing death, is a matter of inches, or a matter of luck, or the differnce between a hit or a near miss.
I do not subscribe to the "no harm - no foul" school of thought. My opinion is that the penalty for dangerous driving should be the same as the penalty for dangerous driving causing death -- very heavy, in both cases.
Smith drives dangerously and goes blandly on his merry way. Jones drives dangerously, and kills three people. The difference is pure happenstance. There should be no difference as to how seriously we regard their two crimes.
