I have not read through the whole thread but I see it this way.
There should be no limit, you should not drink and drive, zero tolerance, and if you do and get caught the punishment should be far tougher than they are now, possibly losing your licence for good.
But today, you are allowed to drink and drive and its tricky to know your limits, while you can drink and drive everybody should carry a breathalyser in the car.
And lastly, and I am not forgiving anyone but a lot of people caught are alcoholics, if anybody has had or still an addiction then you will know that it totally takes over any reasoning I think that if you are an alcoholic or a drug addict somehow you should have your license and vehicle removed until you can prove you have beaten your addiction.
Far too many deaths especially young deaths in the road due to alcohol and drugs.
I do realise how difficult this is to implement but I think we need to get very tough on drink drivers, it's insane that you are allowed to drink and then drive.
Having worked with the alcohol dependence group in West Sussex, (cgl), anyone coming in is required to sign a form stating they will notify the DVLA of their problem, and will be willing to hand in their licence, purely a matter of box ticking tho', and can't believe many people actually do this.
On a separate thing, regarding being over the limit the morning, it is quite interesting how different peoples bodies will respond to this.
For example a very very heavy drinker, (alcoholic?) can drink 3 bottles of wine in an evening and blow zero by 10 the next morning, due to the fact their body is actually allergic ed to alcohol and processes it in a different way, and does everything it can to rid the body of it, hence the need for another drink
