Primary position

The daily Telegraph puts it so well:

Erm ... presumably you also spotted the bits that weren't put very well?

British Cycling’s own safety training, Bikeability, makes it explicitly clear that cyclists must always position themselves at least 0.5 metres from the kerb.

Unfortunately, many cycle lanes in the UK are less than 0.5m in width, which leads to the popular misconception that cyclists belong in the gutter.

(1) It's not 'British Cycling's own safety training'--it's a national standard.

(2) It certainly doesn't contain the advice 'cyclists must always position themselves at least 0.5 metres from the kerb'. Obviously, even being 0.5m out is still 'riding in the gutter'.

(3) I doubt very much that, crap cycle lanes notwithstanding, there's a single cycle lane in the country that's under 0.5m in width.
