I'm not going to start saying we should be allowed to drink a skinful and then drive after. However, not being allowed to drive after 2 pints is ludicrously over the top. Reaction times aren't seriously reduced and there are a lot of very safe drivers out there who could drive safely after 3 or 4 pints so lets just up the limit a little and enable Brits to enjoy themselves again.
Why does this idea matter?
It will boost morale in the country and also reduce the risk of people being caught the morning after when the reality is that they have sobered up and are safe to drive.
