Excellent PSA on the consequences of drink driving.

Wow.... harsh but brilliant.

Drink driving in Britain is social suicide too, for all but scumbags.

I think that's wonderful.
Social pressure---that if you drink and drive, society shuns you, even as you are in the act at the pub---seems to be a powerful social tool

Do the statistics also include improvements to car safety within the last 50 years?

What do you mean? Do you mean they include reductions in deaths because of that? Yes. Do you mean is there an adjustment to try and offset that? No.

Automotive deaths are a raw number, so it shows how many people die in a given area. It isn't something that is adjusted, it is the actual number of people who die. That then gets broken down by the cause.

In general if you are interested in evidence of increased vehicle safety leading to less deaths you can look at the deaths per million vehicle miles traveled. Basically, as people drive more, in general deaths would go up. However better safety in cars has been doing a good job of reducing deaths, despite miles traveled increasing.
