The UK is far more serious about impaired and drunk driving than the US is.

The majority of those people who had their lives cut short cut it short themselves and didn't take anyone with them.

Likewise, that 40k includes 6k pedestrians and 6k motorcyclists.

You can't just take the 40,000 figure and do _anything_ with it because there are so many peculiar modes of accidents which /dominate/ that data set.
