[QUOTE="steve auvache"] Paul Varnsverry wrote Gonna be difficult for the janitors as they do it often enough themselves, I reckon. Poisonally I keep mine down when moving and up when off the bike. And for those who would comment that they like the refreshing airflow when riding slow I have nothing but disdain.[/QUOTE] As indicated up above, I did check the facts with the police officer concerned, and with a friend who visited me earlier today, and who was also with the Met traffic section at the time of the prosecution; and both confirm the facts of the case as I have described them above: case dismissed. The merits of flip-front helmets in permitting mouth-to-mouth resusitation have also been suggested.
