Having half the legal limit in your system is legally and morally right. There is nothing weak willed about it. If you think the legal limit should be zero, don't piss at me and wish me ill. Talk to your MP and work to get it changed.

It is simple, Alcohol is not the only thing that kills on the road and alcohol does not always kill. If it did the solution would be simple. Everyone who drank and drove would be already. But it is not that simple, the reality is that unless you are very very drunk you are quite unlikely to be in an accident on any given trip. You are more likely to be in an accident than a non drinker but you are not likely to be in an accident. I am not saying this to apologize for drunk drivers. I don't. I think it is a profoundly stupid thing to do. I am just saying that more punishment is unlikely to get us much more safety for our law enforcement buck. The approach needs to be comprehensive and proportional; education, punishment, peer pressure.

I am against drinking and driving. I have hope. I think that the police here and the laws here are doing a very good job. I think it is much better now most everywhere than 30 years ago when I was in my 20's. I think it will be even better 30 years from now, Maybe there will be a sensor and a black box in the car measuring and recording the driver's ability to drive.

I stopped inviting a friend to my house because he would get drunk and ride home on his scooter. If he were to get an an accident it is very likely that he would suffer by far the worst of it. But I could not even tacitly condone that. My friend was weak willed. I could not convince him to be stronger. He is no longer my friend.
