The United Kingdom is considereing lowering the legal limit for driving while intoxicated (DWI) to .05. That would be less than a pint of beer of beer at dinner. I am sure M.A.D.D is all over this and will even cite to it when it approaches states like Texas when trying to influence them to lowering their own legal limit.
Currently, our State blood alcohol limit is .08. As late as the last decade the legal limit in Texas was .10. I do not see this being lowered again in the near future. I think most reasonable Texans would agree that one or two drinks at dinner should not be illegal.
