I, OTOH, wouldn't normally cycle after two pints. If I'm going to have more than one I get a taxi, bus, or a lift, or more usually walk.

I *would* therefore describe cycling as alcohol-friendly

Well, this is obviously a matter of semantics at this point, but I'd say that was a strikingly casual use of the phrase. YMMV.

I'd probably still be under the legal limit

Depending on how long you took over it.

If you hadn't been peddling (rather than pedalling:-) urban myths

Well, what can I say? You were right and I was wrong. I am both sorry and better-informed.
