Elwar has the right of it. Hold all accidents to the same standard, and make the guilty party pay, instead of punishing people before they've harmed anyone.
That's fine for people who are ambivalent about the difference between:
- no accident, or
- dead self/spouse/kid and some money + payback.
As always, most people draw a distinction and agree with my way of thinking.
I certainly see a difference between no accident and accident + repayment. But you're
not drawing a distinction between them. You are treating those who did not cause an accident as though they already have. And still you focus on drunkenness.
Driving with a full bladder impairs your ability. Should we prosecute people who drive when they have to pee?
If/when it is a factor in 1/3 of the traffic fatalities, ya, probably.
Particularly if it is completely common knowledge that driving with a full bladder kills thousands of people, it is completely trivial to empty one's bladder and thus not expose others to the danger, and the people who are driving with a full bladder do it so for their own perverse enjoyment like boozers do.
