Well if we accept that wikipedia has statistics correct, in the USA in 2006 about 18,000 people were killed as a result of drunk driving accidents. This compares to the approximate 3000 killed in the 2001 terrorists attacks, so we in the USA accept the number of victims of about one 9/11 attack every two months as a necessary risk of driving, if the cause is a drunk driver.
In the same article, the USA is noted as having a higher DUI rate than either the UK or Australia in spite of both those countries having a lower legal drinking age and higher consumption of alcohol.
