I discussed this in the pub last night, to not a very warm reception from my 40- and 50- something mates. The prevailing view was "I drive fine after a couple", on the basis that they've never had an accident...
I'll drive after a pint, but I won't *plan* to drink & drive. Probably once every month or two. Very occasionally, I'll drive after two, but that will be only if I've chosen something weak (< 4%), I've eaten well, and I'm feeling OK. With a 50mg limit, I'd stick to one, and probably pay more attention to strength.
In reply to skog:
> A -very low- limit, like the Swedish one, might make sense, but is there any evidence to show that dropping the limit further below 50mg/100ml actually improves safety?
A DfT-commissioned report in 2010 suggests cutting from 80mg to 50mg would save between 43 and 303 lives and 280-16,000 serious injuries per year.

In reply to Neil Williams:
I bought a few of those when I was off the booze in January. Tasted like water to me, and I’d rather have a soft drink!
They do Dead Pony Club at 3.8%, which I think is as tasty as Punk IPA (5.6%), but with only 2/3 of the units.
