It has to be said that this is not a new SNP policy - so they are, at least, consistent in their shit-headery.
"What's your problem?" you may be asking. Do I really want more deaths on the road? After all:
Drink driving remains a constant thorn in the side of efforts to make our roads and communities safer. The fact that 1 in 9 road deaths in Scotland were alcohol-related shows we need to do more.
Aaaargh. You utter fucking imbecile. If you want to educate people that drink driving is bad, then educate them - you're in charge of the entire Scottish education system for fuck's sake. You have an enormous PR and media budget. Prioritise the spend. But no, you are trying to change the law. You need (well, okay, you don't, you should have) a reason. A simple change of question for you.
It is not "How many road deaths are alcohol-related?", it is "How many deaths were attributable to the legal alcohol limit being 0.8g/l not 0.5g/l?"
Just one hint. Don't believe the BMA's figure of 65 UK-wide. They, just like our politicians, are another bunch of "Do as we say, not as we do", hypocrites.
* Science pedant here - what, exactly, is wrong with properly labelling this 0.8g/l? Maybe because that seems really small? Cunts.
