I think his insurance is paying out as he is in the US.... and the insurance companies there treat drunk driving differently.
Caveat - What I’m about to say does not mean that I condone drunk driving!!!
In the UK over the course of the last 20-30yrs they have managed to make drink driving taboo. The general public now considers drunk driver to be scum of the earth. The insurance policies reflect these attitudes.
In allot of Europe and the US and certainly in the developing world drink driving is something that is sometimes illegal... but not taboo. There have been no television/political campaigns to try and villainies drunk drivers and so people that do it are not considered to be worse than murderers. The insurance policies in these countries reflect this attitude.
Its 1 of those things that gets people to lynch mob up in this country now, however, using a mobile phone while driving is still something you see often....
