There's a very sensible response
on the Guardian website:
"while it sometimes doesn’t look or feel like our roads are safe, and while it can feel like everyone is out to get everyone else, neither is true. I have rarely encountered real rage while cycling, much less serious near misses. If I wore a helmet camera, the results would be immensely dull. [...]
80% of “cyclists” hold driving licences. We’re the same people"
My best guess is that Boardman made some slightly unguarded comments in a reasonably informal conversation with Helen Pidd, which she turned into a newspaper article. Which is understandable (it's her job) but also slightly disappointing (she's one of the more thoughtful and less sensationalising journalists out there). Despite the posed photos the original piece doesn't read like a set-piece interview, either on paper or on the website - the newspaper has slots for those, and this was printed on the news pages. Maybe there'll be something fuller later.
