It's a pity we have some bloody stupid laws about it as well.
For example, if you go out, get drunk, and stab someone, that's Murder, and involves several years in jail.
If you go out, get drunk and then hit someone with your car, that's causing Death through dangerous driving, which is about 6 months and a driving ban for a few years, which usually get's ignored anyway, and will only come to light if you commit another offence.
Theres a famous case here of where a man who killed 3 members of a family of four people through drunk driving got less of a prison sentence than someone who was picking up golf-balls on a driving range and selling them for charity. Both cases were heard by the same judge in the same court on the same day..
