[Rosie] Not drinking *at all* before you drive is more or less the expected behaviour in this country, so to me there would be no smugness at all in saying such a thing. Hypocricy, possibly, for I'm sure not all who say it adhere to it, but that's a different matter. (I think the actual limit for how much alcohol you're allowed to have in your blood stream is 0.2 promille.)
[Laws] I used to go to work by bike, when I lived and worked in different places to where I live and work now. The bike lane through town was very heavily used during rush hour, and there would always be a few people who would take short-cuts, on the wrong side of the road or on no-biking lanes. I used to ponder over why that made me so annoyed, and realised that it was because the people who do that obviously think that they are worth more than the rest of us. If *everybody* broke *every* law they didn't feel like keeping, chaos and worse would ensue, and very few people think that would be a good idea (including those who blithely ignore speed limits or bike against the flow of traffic, forcing others out of the way). So obviously, only a few people are allowed to do that, because they, and their time, are worth so much more than those of the rest of us. Sorry, I don't buy that. Breadmaster speaks for me, too. Oh, and I also don't drive and don't expect I ever will (I tried to learn once upon a time, and failed. I did learn to fly a glider though, which is much more fun anyway).

I'm also a natural born goody-goody, so I tend to side with Breadmaster too.

I speed. Sometimes. But I also shout at school-run mothers who block the road by parking on the yellow zig-zags, then remove their children from their car seats straight into the road instead of onto the pavement.

I have very little respect for the law per se at all. OTOH I make up for this by having a very highly-developed sense of what is right which I am pretty unbending in following. The reason the Law does not spend much of its time making a pleasant tinkling sound as it breaks in my presence is - surprisingly - because AFAICS on the whole, the Law and What Is Right (in my opinion) are very much congruent.

I do think that surprising because I really think English Law is an ass. So it must obviously get more right than I usually credit it for.
