Sorry guys, but can somebody please highlight the fact that the video is showing the work of the "booze bus", not a conventional emergency ambulance. Go that link to learn about that project which was introduced about 4 years ago to free up other ambulances (which can now go to not-alcohol-related incidents - although that doesn't mean that they don't get too many drunks as well): http://news.bbc.co.uk/1/hi/magazine/7147646.stm
