It's all about social conciousness. For example: A guy is invited to a party and gets loaded. I mean he is drunk. His host or the others in the party who have been drinking sensibly and not drunk, must prevent him from driving back home. In fact they must help him get back there by any means possible.
That's what I mean by "social consiousness" and this is what needs to be aroused in society.
If, on the other hand, friends pump in drinks until bottles get emptied without the least concern about driving home, that's what I call: "social irresponsibility" and awareness of it must be promoted in society.
That is the best way to avoid " driving, if drunk", and not go on advising: "don't drink and drive". This latter slogan is a JOKE. Who on earth skips a drink just because he has to drive? In fact, I drive better after a swig, who doesn't!!!!!
