If there is a principle here that applies to drunk drivers, to be consistent we might need to apply it to more kinds of irresponsible driving than that. And it might convict more of us than we expected.

I lost a good friend (married with young children) to an irresponsible driver many years ago, so I don't have a lot of empathy either.

I still wonder, though, if it would be better to focus on punishing people who actually hurt someone/break something, than punishing people who are irresponsible but got lucky and didn't cause any harm.

Not any easy problem.
