Unswerable question I'm afraid - but thanks everyone.
Thanks for the info WYSIWYG. it was interesting in itself, & I have been very angry with him for being so STUPID as to get so drunk he couldn't even cross a road, leave 3 kids without a father & traumatise the driver I reckon.
I would support no-alcohol-when-driving-law, though I doubt it would be fully enforceable, but how do you stop people drunk walking ?
