Drinking is definitely more socially acceptable in Britain than the US, but that has more to do with differing history (no prohibition) than options for getting home.

Drink driving became socially unacceptable in Britain only in the last 20-30 years but alcohol consumption hasn't really changed. The anti drink driving ads on TV every Christmas were really quite hard hitting. I've seen nothing similar in the US.

The US has extensive ads fighting drinking and driving. I imagine there isn't much difference there.

The UK has had drink driving ads on mainstream TV for 50 years, since 1964.

This BBC page shows some of the ads, and discusses others. http://www.bbc.co.uk/news/magazine-29894885
