The evidence would suggest otherwise, although we could all blether on about this till we're blue in the face, whether you feel alcohol affects your driving ability or not is subjective and dependant on many variables, one pint of normal beer is three units, stronger lager or beer increases that number. Personally, if I'm driving, the vehicle stays at home. The evidence would suggest that 2 units of alcohol increases reaction time by 0.2 seconds, again there are many variables to be taken into consideration, whilst some people may feel that this is also subjective there is research based evidence out there to support it. I respect anyones right to do what they feel is right for them, as for me, if I was to ever hit anyone, and god forbid I ever did, I would like to have a clear conscience that the one pint I had drank hadn't made that difference to my ability https://www.the-alcoholism-guide.org/alcohol-driving.html That is fair enough, though until such point as they bring in a total 0% alcohol consumption and driving I shall continue to have the 1 pint
