I didn't know that. Being a non drinker it's not something that I've needed to know. I just knew Finland was quite low and strict. I just looked it and in the grand scheme of things Finland and Scotland are not particularly low, and the UK is ludicrously high.

0.8 WTF?
Most countries have lower limits for commercial drivers, but not the UK. That's still 0.8.
That's probably not news to most of you who are better informed than me. But seriously, WTF?
Enforcement is another side of it. In Finland they can and do happily stop you and breathalyse you for no other reason than that you are driving a car. In the UK I think they have to have reasonable cause (
@Drago correct me there). In France you have to carry your own little breathalyser. In Ireland the Gardai can't be arsed to enforce it, or indeed do anything at all

All off topic really as the OP is about drink cycling. Sue me.
Edit. It would appear that I've been living under a rock (what's new). This is a live topic of debate. (And as it affects road safety should be ok for CC even if it is technically a political matter). Here's an interesting article.
